To make this simple dish, put 3/4 pounds of dried prunes in a non-reactive saucepan. Add the juice of 1 lemon, 1/3 cup sugar and 1 cup dry Marsala wine. Let stand at room temperature for 2 1/2 to 3 hours.
Cook the prunes over medium heat, lowering heat as needed to keep a good simmer going as they cook. Cook for about 10 or 15 minutes, until the prunes are tender. Pour into a serving bowl and cool to room temperature before serving. These prunes taste even better the next day. Serve at room temperature. This should be enough to feed 4 people.
