- 1 ripe cantaloupe (1 1/2 pounds), halved and seeded
- 1 cup dry white wine
- 1/3 cup sugar
- 1/3 cup water
- 1 strip fresh lime zest
- 1 to 2 tablespoons fresh lime juice
- 2 cups seedless green grapes, halved lengthwise
- Scoop cantaloupe into balls with a melon-ball cutter and reserve rinds.
- Bring wine, sugar, water, and zest to a boil in a small saucepan, stirring until sugar is dissolved. Squeeze juice from rinds into wine mixture. Boil, skimming froth, until reduced to about 1 cup, 15 to 20 minutes. Remove from heat. Discard zest and stir in lime juice.
