Your 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.The 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 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 ❤ As 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.You’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.Add 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.Aren’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 🙂 You 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.Nope. I don’t do boring.
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)
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.
