To make stewed prunes, combine 1 cup water and 1 cup prunes in a saucepan. Bring the water to a boil, cover the prunes, and simmer for 10 minutes. Alternatively, place 1 cup each prunes and water in a microwave-safe bowl, cover the bowl with plastic wrap, and cut several small slits in top of the plastic. Microwave on high for two minutes, or until the prunes are soft.
Another option is to combine 1 cup prunes with 1 1/2 cup water and 1 tablespoon lemon juice. Simmer the mixture over low heat for 20 to 30 minutes, or until the prunes are soft and most of the water is gone. To make cold-stewed prunes, place the mixture in the refrigerator overnight and serve cold.
To make prunes stewed in port wine, combine 1/2 pound dried prunes, 1 thinly sliced Clementine orange, 1 whole cinnamon stick, 1/2 teaspoon ground nutmeg, 1 cup of ruby port and 2 tablespoons of sugar. Add enough water to cover the prunes, and bring the mixture to a boil over medium-low heat. Cover the mixture, and allow it to simmer for 30 minutes, or until the prunes are soft. If necessary, add more water during the cooking process.
