Prepare Watermelon Juice: Start by extracting juice from fresh watermelon. Blend the watermelon pieces, strain, and collect the juice in a bowl.
Combine Ingredients: In a large mixing bowl, combine the watermelon juice and sugar. Stir until the sugar completely dissolves.
Add Corn: Add the corn (or cornstarch) to the mixture and stir well to incorporate.
Incorporate Chopped Watermelon: Fold in the finely chopped watermelon pieces and add a pinch of salt to enhance the flavors.
Whip the Cream: In another bowl, whip the cream until soft peaks form. Be careful not to over-whip!
Mix It All Together: Slowly fold the whipped cream into the watermelon mixture until everything is well blended.
Color It Right: If desired, add a few drops of red food coloring and mix until you achieve your preferred shade.
Churn: Pour the mixture into an ice cream maker and churn according to the manufacturer's instructions until it reaches a soft-serve consistency.
Freeze: Transfer the churned ice cream into an airtight container and freeze for at least 4 hours before serving.
