adapted from 5280 Cookbook
-2 ounces gin (CapRock is delicious; Leopold Bros. Navy Strength is dangerous)
-1/2 ounce Campari
-3/4 ounce lemon juice
-1/4 ounce simple syrup (or to taste)
-1 teaspoon Modern Gingham Raspberry Violet Jam
-6-8 mint leaves
Combine ingredients in a mixing tin without ice, and shake firmly to distribute and dissolve the raspberry preserves. Then add ice cubes, and shake firmly to chill and dilute. Finely strain into a Collins glass full of crushed ice, and garnish with mint sprig and a straw.
