Agua frescas are popular fruit drinks served in Mexico. This one is easy to make at home with pureed watermelon, cranberry juice and lime juice.

Place the melon in a blender or food processor. Process until smooth. Pass the puree through a fine-mesh sieve placed over a bowl to eliminate the pulp and clarify the juice. Pour the juice into a large pitcher. Add the cranberry and lime juices and stir to combine.

Refrigerate until very cold. Pour into tall chilled glasses and garnish each with a slice of lime.

• 2 1/2 pounds seedless watermelon, rind removed and diced (about 7 cups)
• 1 cup fruit-sweetened cranberry juice (sometimes called cranberry nectar)
• 1/4 cup fresh lime juice
• 1 lime, cut into 6 slices
