Garnish: Additional fresh strawberries, mint leaves, lemon wheels, and edible flowers
Pro tip: When making punch for a party, make a backup pitcher and store it in the refrigerator, so you can refresh the punch bowl as the party is going.
In an empty bundt pan or large ice molds, combine strawberries, mint leaves, lemon wheels, and edible flowers and top with ice cubes. Fill with water and freeze overnight.
In a punch bowl, whisk jam, lemon juice, and simple syrup until smooth. Stir in gin and Cointreau, and refrigerate for 1 hour. Just before serving, add sparkling wine, soda, and ice. Finish with additional garnishes.
