Watermelon Ice
Ingredients
Directions
Prepare the watermelon
Save all the juice from the watermelon.
Scrape the red pulp finely.
Add a little water to the pulp, ensuring enough watermelon for a strong flavor.
Freeze and finish
Combine the watermelon liquid with 1 pound of sugar and freeze.
When half frozen, add the well-beaten egg whites.
Stir the mixture frequently from the bottom with a long-handled wooden spatula.

What each ingredient does
- Watermelon
- Provides the main flavor and the liquid base that freezes into the ice.
- Sugar
- Sweetens the ice and lowers its freezing point so it stays softer and scoopable.
- Egg whites
- Beaten in when half frozen, they add air and a lighter, smoother texture.
The step that matters
Adding the egg whites when half frozen. If the mixture is fully frozen, the beaten whites cannot blend in evenly. If it is too liquid, they deflate and the texture turns watery. Stirring from the bottom keeps the whites distributed.
