This dessert-meets-drink is chef Vivian Howard’s favorite way to end a meal, it's easy to see why. Rosemary-infused watermelon sorbet topped with sparkling rosé and fresh fruit is summer refreshment in a glass! (Plan ahead: Watermelon sorbet and ice cream canister require overnight freezing.)
Watermelon-Rosemary Sorbet: Freeze the canister of an ice cream or sorbet maker overnight (or according to manufacturer’s directions). Meanwhile, prepare a simple syrup by combining water, sugar, and rosemary sprigs in a small saucepan. Over medium-high heat, bring to a simmer, uncovered, then immediately turn off heat and let rosemary steep as syrup cools to room temperature, 10 minutes.
Remove and discard rosemary sprigs. Pour syrup into a blender, then add watermelon, lime juice, and tequila. Cover and blend until smooth. Place a strainer over a storage container and strain watermelon mixture, separating the pulp and foam from the liquid; discard pulp and foam. Cover and chill liquid overnight in the refrigerator. (Alternatively, mixture can be chilled quickly by placing the container into an ice bath.)
Set up ice cream maker and pour watermelon base into the frozen canister. Turn on and churn mixture until it’s thick and looks frozen, about 30 minutes. Transfer sorbet into a container and freeze, covered, at least 2 hours. Makes 1 quart.
Assembly: Place a scoop of sorbet into a chilled glass; add a tablespoon each of diced peaches and blueberries. Top with sparkling rosé and serve immediately, with a spoon, straw, or both.
