Watermelon revisited

I bought a watermelon and it turned out to be over ripe. It wasn't all that pleasant to eat so I had to decide whether to get rid of it or find something else to do with it. So, tomorrow I'm going to try and make watermelon ice. It isn't complicated but what will it taste like?

Ingredients:

1/2 small watermelon, pelled, seeded and cut into 1 chunks (about 6 cups) 3 tablespoons confectioner's sugar 1 tablespoon lemon juice 1/4 teaspoon salt

Instructions:

In covered blender at low speed blend 1 cup of the watermelon chunks with confectioner's sugar, juice and salt until smooth; add remaining watermelon and blend until smooth. Pour into a 9" x 9" baking pan; cover with foil or plastic wrap and freeze until partially frozen, about 2 hours. Spoon watermelon mixture into a large, chilled bowl. With mixer at high speed, beat until fluffy. Return mixture to baking pan and freeze until firm, about 1 1/2 hours. To serve: Remove from freezer and let stand for 10 minutes at room temperature for easier scooping.
