It's super easy and no ice cream maker necessary!
You will need:
- 3 cups watermelon puree ( just puree in your blender)
- 1-1/2 cups heavy cream
- 3/4 cup buttermilk
- 2/3 cup sugar
In a large mixing bowl, combine watermelon puree, heavy cream, buttermilk, sugar and a few drops of red food coloring (optional). Stir the mixture until sugar is dissolved.
Transfer to a 9 x 9 x 2 inch pan. Cover and freeze 2 to 3 hours or until almost firm.
Break the frozen watermelon mixture into chunks. Beat with an electric mixer until smooth, but not melted.
Cover and freeze until firm. Makes 1-1/4 qts.
Note: I preferred this sherbet soft-serve consistency. After it was frozen firm, I micro-waved it for 30 seconds, then beat it again with the mixer and it was smoother and creamier.
