Alcoholic Herb and Pink Lemonade Jellybutter

⅓ cup frozen pink lemonade concentrate, thawed

⅓ cup water

½ tablespoon each minced fresh parsley, thyme, and rosemary

⅛ teaspoon salt

¼ pound softened unsalted butter

1 envelope (¼ ounce) gelatin

⅓ cup vodka

Lemon zest, for garnish

1. In a large measuring cup, combine the lemonade concentrate with water; strain into a medium saucepan.  Mix herbs, salt, and butter into lemonade mixture.  Sprinkle gelatin over the mixture and let soften for 2 minutes.  Heat over low heat, stirring constantly, until the gelatin is dissolved, about 5 minutes; stir in the vodka.
2. Pour mixture into a 4-by-8-inch loaf pan and refrigerate until firm, about 4 hours.  Serve as a loaf; garnish with lemon zest.
