Pineapple Gin Punch

Hint: Use triple sec in place of Cointreau. It's 10% the cost, and this is a mixed drink featuring gin and pineapple juice.

Ingredients
3 cups pineapple juice
3/4 cup fresh lemon juice, plus lemon twists, for garnish
12 ounces gin
4 ounces orange liqueur, such as Cointreau
1/2 teaspoon allspice
Champagne or sparkling wine, chilled, for serving

Directions
Combine the pineapple juice, lemon juice, gin, orange liqueur and allspice in a pitcher filled with ice. Stir to combine. Pour into ice-filled highball glasses, top with champagne and garnish each with a lemon twist.
