Spiked treats make an annual appearance at Christmastime in the form of bite-size chocolate rum balls and brandied eggnog, but some cooks like to keep the party going in the kitchen year-round.

“I cook with booze all the time,” says Jen Templeton, owner of Gingersnap Sweets & Such in Chicago. A whiskey enthusiast and former Julius Meinl pastry chef, Jen can be found infusing caramel truffles and tarts with bourbon or preparing fruits in cordials and brandies in just about any season. She even makes use of malted barley, a beer byproduct acquired from a local brewery, to make graham crusts for cakes.

On the Rocks or on a Cake

Liquor can lend desserts a hint of unique flavor or a full-on adult-beverage kick. Using spirits in the kitchen instead of behind the bar is nothing new, of course. Wee drams of whiskey are often found in traditional Scottish and Irish desserts, and Bon Appetit magazine has run many a feature on the bourbon-laced desserts of Kentucky Derby day. For delicate mousses that require subtle whiskey notes, Jen reaches for top-shelf labels such as Templeton Rye and Eagle Rare. In a pecan pie or a rich cake, something that can stand up to a bolder bourbon twang, she said cheaper brands such as Jim Beam work just fine.

Plays Well with Fruit

Champagne gets used in gelées, jello's sophisticated antecedent, as well as sabayons, a type of light, whipped custard—both of which pair perfectly with the sweetness of summer berries. Berries welcome the flavor of many types of liquor, and Jen reveals—maybe surprisingly—that "blueberries and gin are actually a really beautiful pairing.” When making a blueberry dessert, such as a compote, most people finish their berries off with a bit of lemon juice for brightness; but Jen adds in a splash of gin for an element of depth and a slightly savory accent.

Tips for Trying it at Home

Anyone who's watched an episode of Good Eats or America's Test Kitchen knows there's a fair bit of chemistry that goes into baking, so you can't just go adding shots of whiskey to a bowl of batter and pop it in the oven. Jen warns home cooks to remember that when considering liquid substitutions in a recipe, oil is considered a fat, not a liquid. Even though it’s pourable, it cannot be swapped out for booze.

Below, Jen shares two recipes that will help you get the libations brewing in your baking.
