3 cups watermelon
2–3 tbsp honey or maple syrup
1 tbsp lime or lemon juice
A pinch of salt
Deseed watermelon and cut it into cubes. Freeze for 3-4 hours.
Once watermelon cubes are frozen, blend it into a smooth slushy.
Add lime juice, a pinch of salt, and sweetener to adjust sweetness. Blend until creamy.
Pour the mixture into a cake or ice cream tin. Freeze for 1-2 hours for firm texture. Once frozen to desired consistency, scoop into glasses and serve.
