Loosely based on the French 75, a classic cocktail of gin, Champagne, lemon juice, and sugar, this sparkling beverage uses lemonade concentrate as a shortcut. Be sure to allow the concentrate to thaw ahead of time. You'll use almost a whole bottle of Champagne; the rest goes into the dessert. If time allows, you can use a quick simple syrup with lemon juice: Combine 3 tablespoons each of sugar, lemon juice, and water; microwave for 1 minute, and cool.
1 cup gin, chilled
1/2 cup frozen lemonade concentrate, thawed
2 2/3 cups Champagne or other sparkling wine, chilled
Tarragon sprigs (optional)
How to Make It
Combine gin and lemonade concentrate in a pitcher; chill until ready to serve.
Just before serving, add Champagne to gin mixture; stir gently. Garnish with tarragon sprigs, if desired.
