Into a clean ice cream churn pour two cans sweetened condensed milk, one quart whipping cream(substitute half and half for low fat). Chill in the refrigerator. Whirl a cup of fresh fruit, 1 teaspoon vanilla, and 1 cup of milk(skim for low fat) in the blender. Add this mixture and 1 cup chopped fruit to the chilled churn. Add milk to the fill line. Put in the dasher and put on the top. Churn with rock salt and ice until firm. Carefully remove and wipe off the container-salt will ruin the ice cream. Take out the dasher and place ice cream in freezer to ripen and freeze. If you can stand it, wait at least two hours. Then serve and enjoy.
