How to Make It
Combine 3 Tbsp. (1 1/2 oz.) white whiskey, 1 1/2 Tbsp. (3/4 oz.) Grand Marnier or other orange-flavored liqueur, 1 Tbsp. fresh lime juice, 1 1/2 tsp. Blackberry Farm Blackberry Preserves, and 3 fresh blackberries in an ice-filled cocktail shaker. Cover with lid, and shake until mixed and thoroughly chilled, about 45 seconds. Strain whiskey mixture into an old-fashioned glass filled with crushed ice. Garnish with fresh blackberries and lime peel twists.
