Grapefruit Pie with Oreo Crust

Grapefruit Pie with Oreo CrustLast Pi Day (March 14th aka 3.14 aka π), I posted a recipe for Pecan Pie Kolaches that was mostly just me saying “What is happening? What is happening? Here’s a recipe, I guess,” and trying not to have a full-scale meltdown while the world closed up. Needless to say, this year’s post is a little less dramatic.

Except for the pie. It’s bringing all the drama in the best possible way. The colors, the textures, the slightly unusual flavor combination–it’s everything I want these days.Grapefruit Pie with Oreo CrustGrapefruit Pie with Oreo Crust is out of this world delicious and a stunner to boot. Crumbly Oreo crust is filled with a soft and tangy Grapefruit filling and finished with whipped cream, chocolate curls and thin strips of grapefruit zest.Grapefruit Pie with Oreo CrustIf you think I’ve lost my mind combining grapefruit and chocolate, know that I would have turned my nose up at this just a few years ago. However, after trying key lime and chocolate together, I am sold. The tang of citrus and the bitterness of chocolate are a perfect pairing. Try it—you’ll love it.Grapefruit Pie with Oreo CrustThis pie is pretty simple to make, but as with most simple things, it does require some preparation. The filling is a play on my Lemon Meringue Pie, wherein the structure mostly comes from egg yolks and cornstarch. It’s a lot like making homemade pudding, which is really no big deal.

Cornstarch, sugar, salt and water are whisked together over medium heat until thick. This mixture is used to temper (warm) the egg yolks, before it’s all simmered with a grapefruit reduction and a hint of lemon juice. Whisk in a little butter, pour it through a sieve and voila! Grapefruit pie filling.

(I think I may have accidentally made it sound complicated by laying the method out like that, but I promise you it’s simple and comes together quickly.)Grapefruit Pie with Oreo CrustOnce the filling and crust are prepared, it’s just a matter of pouring one into the other and letting them get nice and cold together. This cannot be rushed, so plan ahead. Grapefruit Pie with Oreo CrustGrapefruit Pie with Oreo CrustWhen Grapefruit Pie with Oreo Crust is completely chilled, it will still be a little on the jiggly side, like a citrus curd with a little more body. After you add a flourish of whipped cream and the garnishes of your choosing, you’ll be treated to a tart, sweet, creamy, crumbly confluence of goodness. The cream offsets the tanginess of the filling, and the buttery chocolate crumb crust rounds it all out. This pie is rich and refreshing–the perfect way to start what will hopefully be a much simpler twelve months for us all.

Happy Pi Day, y’all. Grapefruit Pie with Oreo Crust

Grapefruit Pie with Oreo Crust
makes one 9-inch pie

Oreo Crust:
24 Oreos
5 tablespoons unsalted butter, melted

Grapefruit Filling:
2 cups fresh grapefruit juice (from about 3 medium-large grapefruits)
1 cup granulated sugar
1/4 cup cornstarch
1/4 teaspoon Kosher or sea salt
1 1/3 cup water
5 large egg yolks
1 tablespoon fresh grapefruit zest
1 tablespoon fresh lemon juice
2 tablespoon unsalted butter
1 teaspoon pure vanilla extract
1 drop red liquid food coloring (optional)

Whipped Cream & Garnish:
1 cup heavy cream, very cold
4 tablespoons confectioner’s sugar
grapefruit zest (strips or grated)
chocolate curls

Preheat oven to 350F. Lightly grease a 9-inch pie plate.

Make the crust. Place Oreos in the bowl of a food processor and blitz until they are crumbs. Add melted butter and pulse until the mixture can be pinched together. Press it into the bottom and up the sides of the pie plate (I find that a 1/4 cup measuring cup helps with this). Bake the crust for 10 minutes and then let it cool while you make the filling.

Pour grapefruit juice in a small saucepan. Bring to a boil over medium-high heat and cook until reduced to 1 cup (about 10-12 minutes). Remove from heat and cool 5 minutes.

In a small mixing bowl, use a fork to beat egg yolks. Set aside.

In a large saucepan, whisk together sugar, cornstarch, and salt. Whisk in water. Heat over medium heat, stirring frequently, until the mixture reaches a simmer and thickens. Turn heat to low.

Whisking constantly, pour 1/3 cup of the mixture into the bowl of egg yolks until fully combined. Whisking constantly, add egg yolk mixture back to the pan. Return heat to medium. Stir in grapefruit zest, followed by grapefruit reduction and lemon juice. Continue whisking until the mixture has boiled for 1 full minute. Remove from heat. Whisk in butter, vanilla and optional red food coloring. Push filling through a sieve to remove solids.

Pour filling into crust. Gently tap the pan on the counter a few times to help air bubbles disperse. Pop any surface bubbles with a toothpick as needed. Let pie cool to room temperature, then chill for at least 4 hours. Filling will be set, but jiggly, when ready.

Just before serving, make whipped cream. Combine heavy cream and confectioner’s sugar in a large mixing bowl. Use an electric mixer to whip the mixture on low for 30 seconds before whipping on high for 1-2 minutes, or until stiff peaks form.

Load whipped cream into a piping bag fitted with a large star tip. Pipe as desired over the top of the pie. Garnish with grapefruit zest strips and/or chocolate curls, if desired.

Slice pie with a large, sharp chef’s knife, wiping it clean between cuts. Serve immediately.

Pie is best upon assembly, but leftovers may be kept in the refrigerator for a day. The filling may weep a tiny bit over time.

Friday Favorites: 2020Happy New Year! This post is coming at you from the recent past—December 29th—so I hope no new terrible things have happened between then and this posting. 2020 was such a weird year. It started off okay, but quickly devolved to…well, whatever this is. I, for one, am hoping for hope in 2021.

As a preface to this list, I wrote three paragraphs about the events of last year (staying at home, flour shortage, bread, people learning to bake, blah blah blah) and then deleted them because, you know, you were there. It was a year where nearly everything changed, but at least one thing remained the same: I was here, baking in Brooklyn. Here are some of my personal favorite recipes from 2020.Friday Favorites: 2020

Grapefruit Sandwich Cookies

Grapefruit Sandwich Cookies Oh y’all, I have winter citrus on my mind. Meyer Lemon Sweet Rolls, Orange Cardamom Cake, Key Lime Linzers, Lemon Poppy Seed Muffins—if you can throw zest or juice into it, I. am. interested.

That goes double for these Grapefruit Sandwich Cookies, which contain plenty of fresh grapefruit zest and juice, and even have some extra zip from a lemon! They’re a little on the soft side with huge citrus flavor—perfect for a party, late night dessert, or pairing with a cup of tea. If you are looking for a recipe to drag you out of the winter doldrums, this is it.Grapefruit Sandwich CookiesGrapefruit Sandwich Cookies are exactly what they sound like. The cookies themselves are a variation on my favorite sugar cookie dough. I nixed the cream cheese in favor of more butter, reduced the baking powder and threw in some grapefruit zest for obvious reasons. They’re baked until they’re just barely done, about 6 minutes.Grapefruit Sandwich CookiesThe filling is the completely stellar Grapefruit Curd that I made for kolaches a couple of years ago. It takes some zesting, juicing and whisking, but it’s actually incredibly simple to make. Just make sure to make it ahead so it’s fully chilled by the time you want to assemble.Grapefruit Sandwich CookiesPipe it almost to the edges. You want the curd to peek out the sides.Grapefruit Sandwich CookiesYou may certainly eat these cookies right after assembly, but I highly recommend refrigerating them for about 6 hours before doing so. This allows the curd to set and the cookies to soften slightly so that everything stays in place when you bite in. You know, instead of falling apart in your hands. Not that that’s a bad thing.Grapefruit Sandwich CookiesYou’ll notice that the batch makes 8(-ish) dozen cookies. Don’t let this scare you off! The cookies are teeny, made with a 1 1/2-inch cutter, and will keep for approximately eternity (…or a week) in the fridge. If you want to make fewer larger cookies, feel free to use a 2 1/2-inch cutter and maybe give them an extra minute in the oven. I’m pretty fond of these little gems though. Anything that allows me to eat five cookies in one sitting is okay by me.Grapefruit Sandwich Cookies

Grapefruit Sandwich Cookies
makes 8-ish dozen very small cookies

3 1/4 cups all-purpose flour
1 teaspoon baking powder
1/2 teaspoon Kosher or sea salt
1 cup granulated sugar
2 tablespoons ruby red grapefruit zest (from about 1 1/2 grapefruits)
1 cup (2 sticks) unsalted butter, softened to room temperature
1 large egg, room temperature
1 teaspoon pure vanilla extract

Filling:
1 recipe Grapefruit Curd, made ahead & chilled (recipe below)

Special Equipment:
rolling pin
cookie cutters

Read through this recipe before beginning. The grapefruit curd will need to be made ahead of time and the assembled cookies are best after a 4-6 hour chill.

In a large mixing bowl, whisk together flour, baking powder, and salt. Set aside.

In a separate large mixing bowl, use your fingertips to rub grapefruit zest into sugar. Add butter and use an electric mixer to beat until light and fluffy, about 2 minutes. Mix in egg and vanilla. Add dry ingredients in 3 installments, combining completely after each. Divide dough into quarters.

Working with one quarter at a time, sandwich dough between two pieces of parchment paper and roll until 1/8-inch thick. Transfer to the freezer (on a baking sheet, if desired) for 15 minutes. Repeat with remaining dough. It is okay to stack the sheets of dough in the freezer.

While the dough is freezing, preheat the oven to 350F. Line two baking sheets with parchment. Set aside.

Remove one sheet of dough from the freezer. Peel on of the pieces of parchment off. Use a lightly floured 1 1/2-inch round cookie cutter to cut cookies. Place them at least 1 inch apart on prepared pans. Repeat with remaining dough. Scraps can be re-rolled, frozen, and cut.

Bake cookies 6-7 minutes, until no longer raw looking. Let cookies cool on the pans for five minutes before removing to a rack to cool completely. Repeat rolling, cutting, and baking with any remaining dough.

To assemble sandwich cookies, place half the baked cookies on a surface bottom-side-up. Load grapefruit curd into a piping bag and snip a small corner. Pipe filling almost to the edge (1/8-1/4-inch blank border on all sides) on each cookie before gently topping with another cookie, bottom-side-down. Repeat until all cookies have been filled.

Place filled cookies on a rimmed baking sheet (or other large-ish pan) and chill for 4-6 hours or overnight before serving. This will slightly soften the cookies and keep the curd from squishing out when you take a bite.

Cookies will keep in an airtight container in the refrigerator for up to a week.

Grapefruit Curd
makes about 1 1/3 cups

1 1/2 cups fresh-squeezed ruby red grapefruit juice, from about 2 large grapefruits
2 tablespoons grapefruit zest, from about 2 large grapefruits
1/2 cup granulated sugar
pinch of salt
1 tablespoon fresh-squeezed lemon juice, from about 1/2 medium lemon
1 large egg + 3 large egg yolks, room temperature
6 tablespoons unsalted butter, cut into 24 small cubes

Pour grapefruit juice in a small saucepan. Bring to a boil over medium-high heat and cook until reduced to 2/3 cup (about 12-15 minutes). Remove from heat and cool 5 minutes.

Fill a small pot with 1-2 inches of water. Set a heatproof bowl over the top, ensuring that the water does not touch the bottom of the bowl. Remove bowl and bring water to a simmer.

In the heatproof bowl, whisk together grapefruit zest, sugar, warm grapefruit reduction, lemon juice, and eggs. Set bowl over the pot of simmering water. Whisk constantly until mixture thickens slightly (it should coat the back of a spoon). Add butter 1-2 cubes at a time, whisking until melted. Continue until all butter is used. This should take 11-15 minutes total.

Set a fine mesh sieve over a medium mixing bowl. Push curd through sieve to remove zest. Transfer curd to a jar (or other container) and press a piece of plastic wrap to the top. Chill well.Grapefruit Sandwich CookiesGrapefruit Sandwich CookiesGrapefruit Sandwich Cookies

Sparkling Grapefruit-Lime Aguas Frescas

Sparkling Grapefruit-Lime Aguas FrescasYour eyes are not deceiving you. I’m posting a cold beverage on a sub-30F day here in NYC. If you think I’ve lost my mind, you’re late to the party—I’ve been known to make ice cream in February.Sparkling Grapefruit-Lime Aguas FrescasThe truth is that a small miracle occurred a couple of weeks ago when I managed to find better-than-decent ruby red grapefruit for a third time this winter, something that’s virtually unheard of in New York. I’m lucky to find quality grapefruit once per year (see here, here, and here), so three times is just…well, it’s making my inner Texan very happy. I try to keep that part of myself under control, but it’s very difficult around good South Texas citrus (and enchiladas), so here we are.Sparkling Grapefruit-Lime Aguas FrescasSparkling Grapefruit-Lime Aguas Frescas are exactly what I want in these last weeks of winter. They’re a fruity, bright, seasonal, sippable reminder that there will soon be a day when I can leave my coat at home. If you’ve never heard of an agua fresca, it’s just a combination of fresh fruit, sugar, and water. I made a Spicy Mango version last summer that’ll knock your socks off, and I’m excited to be adding a wintry version to my repertoire today ❤ Sparkling Grapefruit-Lime Aguas FrescasAs their name states, these aguas frescas are made with fresh-squeezed grapefruit and lime juices. They’re mixed together in a pitcher (or a big measuring cup, if you’re me) and sweetened to taste with a little simple syrup. I don’t care for super-sweet beverages in general, so I tend to limit the syrup to 1/3 cup for the entire batch, but feel free to sweeten to your heart’s content.Sparkling Grapefruit-Lime Aguas FrescasSparkling Grapefruit-Lime Aguas FrescasYou’ll also need simple syrup for salting the rims of your glasses. Salt is totally dreamy with both grapefruit and lime, so this is one lily worth gilding. Just dip the rim of each glass into a dish of simple syrup and then into salt. Voila! A salted rim 🙂 I used regular Kosher salt here, but anything slightly coarse will do.Sparkling Grapefruit-Lime Aguas FrescasSparkling Grapefruit-Lime Aguas FrescasSparkling Grapefruit-Lime Aguas FrescasAdd a few ice cubes to each of your salt-rimmed glasses and then fill them 3/4 full of the juice mixture. Most aguas frescas are blended with regular cold water, but I like to top these off with a little sparkling water. I use Topo Chico and love the subtle fizz it provides.Sparkling Grapefruit-Lime Aguas FrescasAren’t these fun?! I love their bright color and fresh, tangy flavor, and those salted rims, of course. They remind me a lot of a Salty Dog cocktail (aka grapefruit + vodka/white tequila + salt), but without the booze. I may or may not have taken to calling these Salty Schnauzers 🙂 Sparkling Grapefruit-Lime Aguas FrescasYou may, of course, add liquor to the mix, but as someone who doesn’t drink anymore, I’m always thrilled when there’s an alcohol-free option that isn’t soda, juice, or plain seltzer. I may be sober, but that doesn’t mean I only drink boring drinks.Sparkling Grapefruit-Lime Aguas FrescasNope. I don’t do boring.Sparkling Grapefruit-Lime Aguas Frescas

Sparkling Grapefruit-Lime Aguas Frescas
makes about 6 servings

2 1/2 cups fresh ruby red grapefruit juice (about 3 large grapefruits)
1/2 cup fresh lime juice (about 2-3 large, juicy limes)
1/3-1/2 cup simple syrup* (method in recipe notes)
ice
12 ounces sparkling water (I like Topo Chico)

For the salted rims:
1/4 cup Kosher or other coarse salt
1/4 cup simple syrup

In a pitcher or large (4+ cup) liquid measuring cup, stir together grapefruit and lime juices and simple syrup. Set aside.

Salt the rims of the glasses. Put simple syrup in a wide, shallow bowl. Make a bed of salt on a small plate. Working with one small glass at a time, dip the rim of each glass into the simple syrup and then into the salt. Repeat with remaining five glasses.

Place a few ice cubes in each glass. Fill 3/4 full with juice mixture and top each with a little sparkling water. Drinks will fizz (but not overflow) when mixture hits the salt rim. Serve immediately.

Aguas frescas will separate slowly as they sit; counteract this with a light stir. Any leftover juice mixture will keep covered in the refrigerator for a day or so.

Note: To make simple syrup, combine 1/2 cup granulated sugar and 1/2 cup water in a small saucepan over medium-high heat. Bring to a simmer, stirring frequently, until sugar has dissolved (about 5 minutes). Remove from heat. Let cool for 5-10 minutes before using. Leftovers can be kept in a sealed container in the refrigerator.Sparkling Grapefruit-Lime Aguas FrescasSparkling Grapefruit-Lime Aguas Frescas

Grapefruit Bars

Grapefruit BarsTexans love a ruby red grapefruit, and while I have not been a resident of my home state for more than a decade, my mid-winter citrus needs are still very real. Unfortunately, the window for finding spectacular grapefruit in NYC is alarmingly short—just a few weeks!—and so I am compelled to take advantage. It’s my duty as a displaced Texan. Or something.Grapefruit BarsGrapefruit Scones, Curd and Kolaches have all made appearances on this blog, and today I’m adding another recipe to my favorite winter citrus arsenal: Grapefruit Bars!Grapefruit BarsThese beauts are a seasonal spin on their more traditional lemony counterparts, but with all the sweet-tartness and vivid color of ruby red grapefruit.Grapefruit BarsNow, if you’ve ever cooked with grapefruit, you might have noticed that it tends to lose its natural color and tartness as it is heated. I learned to mitigate this last year while testing Grapefruit Curd, and bring some of the same techniques to making the filling for these bars.Grapefruit BarsGrapefruit BarsGrapefruit BarsHere, grapefruit flavor is added in two ways: first, by reducing a cup of fresh grapefruit juice by half, and then by rubbing zest into granulated sugar to release the citrusy oils. I also like to add a couple of tablespoons of lemon juice to ensure that the bars have a tart finish. The idea of omitting the lemon in favor of a “pure” grapefruit flavor is tempting, but I promise that leaving it out will leave you missing the acidic sharpness that makes these bars so singularly great.Grapefruit BarsThe sweet-tart ruby red grapefruit flavor pairs perfectly with the lightly-squidgy texture of the filling—it’s the sort of thing I daydream about sinking my teeth into. Really. I have caught myself thinking about the feeling of taking the first bite into a Grapefruit Bar more than a few times since I finished testing these a couple of weeks ago. Is that not normal?Grapefruit BarsIf not, I don’t want to be normal. Life’s too short not to daydream about the feeling of soft-set grapefruit filling and crisp, buttery shortbread between your teeth. It’s that sort of wholesomeness that makes this whole being a professional homebaker thing worthwhile.Grapefruit Bars

Grapefruit Bars
makes 16 bars

Grapefruit Filling:
2 large ruby red (or pink) grapefruits
1 cup granulated sugar
2 tablespoons fresh lemon juice (about 1 medium lemon)
2 large eggs + 1 large egg yolk, room temperature
4 tablespoons unsalted butter, melted
2 tablespoons all-purpose flour
1/4 teaspoon Kosher or sea salt
1 drop red food coloring (optional)

Shortbread Crust:
1 cup all-purpose flour
1/4 cup granulated sugar
1/4 teaspoon Kosher or sea salt
1/2 cup (1 stick) unsalted butter, very cold, cut into cubes

Topping:
3-4 tablespoons confectioner’s sugar

Preheat the oven to 350F. Line an 8- or 9-inch square pan with aluminum foil, leaving overhang on two sides for removal. Grease with butter. Set aside.

Zest and juice grapefruits. Set zest aside. Pour 1 cup* of the juice into a saucepan and simmer over medium-high heat until reduced to 1/2 cup, about 10-12 minutes. Set aside.

Make the shortbread crust. In a large mixing bowl, mix together flour, sugar, and salt. Using a pastry blender or two forks, cut butter into dry ingredients until the largest pieces are the size of small peas. Mixture will be very crumbly and dry. Transfer mixture to prepared pan and use your fingertips to press it into one even layer on the bottom of the pan. Bake for 10 minutes. Cool on a rack for a few minutes while you prepare the filling.

In a large mixing bowl, combine reserved grapefruit zest and sugar. Use your fingertips to rub zest into sugar until combined. Whisk in grapefruit reduction, lemon juice, followed by eggs and egg yolk, and melted butter. Mix in all-purpose flour and salt. Add food coloring, if using. Mixture will be thin. Pour filling over the shortbread crust. Bake for 18-20 minutes. Let cool completely on a rack before chilling for at least four hours.

Use the foil overhang to remove bars from the pan to a cutting board. Peel foil from the edges. Use a large, sharp chef’s knife to slice bars. Sift confectioner’s sugar over the tops of the bars before serving.

Serve bars immediately or refrigerate for up to three days. Confectioner’s sugar will degrade over time—this can be remedied by sifting more over the tops.

Note:

If you have slightly more or less juice, that’s okay. Just reduce it to 1/2 cup, as indicated in the recipe.
