Preparation Bring sugar, water, and lemon juice to a boil, stirring occasionally until sugar is dissolved, then boil, uncovered, until slightly thickened, about 5 minutes. Stir in cantaloupe and raisins and simmer, uncovered, stirring frequently, until cantaloupe is translucent and syrup is thickened, 15 to 20 minutes. Transfer conserve to a metal bowl, then set bowl in a larger bowl of ice and cold water to cool, stirring occasionally.
