With lemon, orange, and grapefruit trees that are at least 10, 20, and 30 years old, respectively, this time of year is a citrus bonanza in my backyard.
And though there’s no shortage of fruit in the kitchen, I hate letting any part of it go to waste. I zest, squeeze, and juice my way through baskets of citrus every week, but what can you really do with a few cupfuls of zest? (You can only freeze so much of it.)
The answer: citruscello. (Or in this case, grapefruitcello and orangecello.)
A couple of years ago I shared my recipe for homemade limoncello, a bright and boozy concoction that originated in Italy but you don’t need your own Sorrento lemons to craft your own. I make mine with homegrown Eureka lemons (the thick skin is ideal for zesting) and these days, I also do up smaller batches of grapefruitcello and orangecello using Oro Blanco grapefruit zest and Valencia orange zest (sometimes even mixed together!).
My citruscello tends to be on the stronger side as I like to use it as a mixer, but if you let yours sit and age for a few months, the bite definitely mellows and the liqueur becomes a a lot smoother. This is not meant to be consumed in big gulps, anyway; a chilled cordial glass filled with cold citruscello is all you need. You want to enjoy every luscious sip over good conversation with company after a leisurely three-hour dinner, the way the Italians do it.
My original batch of limoncello made quite a lot (as the liqueur can be divvied up into smaller bottles for gift-giving), but this recipe makes a more manageable amount… so you can try a few different flavors at once! Each 750 ml bottle of Everclear (or vodka) fills a mason jar with room to spare for the zest. Once mixed with simple syrup, you’ll end up with 1 1/2 quarts in the batch, which you can further sweeten with more syrup if desired.
I won’t repeat all the detailed directions from this post (do read it first before you move on), as the process is the same no matter which citrus you use, but here are a few key points to keep in mind:
- Use organic, blemish-free citrus, and scrub them clean before zesting
- A Microplane makes easy work of all that zesting you have to do
- 151- or 190-proof Everclear is my preferred alcohol for extracting the citrus oils, but you can also use a mid-grade vodka in the highest proof you can find (minimum 100-proof)
Small-Batch Grapefruitcello and Orangecello
Makes 1 1/2 quarts
8 to 10 grapefruits or oranges
1 (750 ml) bottle high-proof pure grain alcohol
3 cups water
2 cups sugar
Zest your fruit, taking care to remove only the outer yellow or orange peel (and not the white pith underneath). I usually end up with around 1/2 cup (up to 1 cup) of zest per batch.
Dump the zest into a 32-ounce jar and pour the alcohol over it. Seal with a lid and store in a cool and dark place. Steep the zest for at least three weeks (if using Everclear) or six weeks (if using vodka) until the zest turns white and brittle.
To make the simple syrup, combine the water and sugar in a medium saucepan over medium-high heat. Bring to a boil and stir until the sugar is dissolved. Let cool to room temperature before using.
Pour half of the lemon-infused alcohol into a second jar (or reuse the empty Everclear bottle), then fill each jar with an equal amount of simple syrup. No need to fuss with the zest for now; just let them sit until the liqueur is ready to be strained.
After one to two weeks (or even longer for better flavor), strain both jars of citruscello through a fine mesh sieve into a large pitcher, then strain again through an ultra fine sieve (like a gold coffee filter or several layers of cheesecloth) as you pour the cello back into the mason jars. You’ll fill each jar just over halfway full; add more simple syrup if you like it a little sweeter, but I recommend waiting at least a month for the flavor to mellow out before you decide how much more to add. You might not need to at all, and in the meantime, you can use the potent “young” cello as a mixer.
Store the cello in the freezer and serve in chilled glasses for a refreshing digestif, or stir into champagne or gin for a boozy cooler.
