Here is a recipe for a neat drink.
German Chocolate Cake Martini
2 cups ice
2 ounces citrus vodka
2 ounces hazelnut liqueur
1 fresh lemon wedge
1 teaspoon sugar
Fill a shaker with ice. Add vodka and hazelnut liqueur and shake
to combine. Dip lemon wedge into sugar. Strain vodka and hazelnut liqueur into a snifter or lowball glass.
Bite lemon with sugar, then drink from snifter. Swallow, then exhale. Tastes just like German chocolate
