Notes
For a pitcher: To make 6 cocktails, combine 9 ounces vodka, 18 ounces lemonade, and 3 ounces raspberry liqueur in a pitcher. Refrigerate until ready to serve. Pour over ice and garnish with honeydew melon balls.
Make-ahead: Stir together the vodka, lemonade, and raspberry liqueur up to 1 day ahead. Store covered in the refrigerator. Add ice and garnish just before serving.
Non-alcoholic version: Use lemonade, a splash of cranberry juice, a squeeze of fresh lime juice, and honeydew melon balls. Top with club soda or sparkling lemonade if desired.
Substitutions: Use another raspberry liqueur if you do not have Chambord. Store-bought lemonade works well, but tart lemonade gives the best balance.
Troubleshooting: If the cocktail tastes too sweet, add a squeeze of fresh lemon juice or a splash of club soda. If it tastes too tart, add a little more lemonade.
