Why it works: Sugar and lemon are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Watermelon Ice
Ingredients
Directions
Make the base
Blend 1 cup watermelon chunks with confectioners' sugar, lemon juice, and salt in a covered blender at low speed until smooth.
Add remaining watermelon chunks and blend a few seconds longer until smooth.
Pour mixture into a 9" by 9" baking pan, cover with foil or plastic wrap, and freeze until partially frozen, about 2 hours.
Whip and freeze
Transfer partially frozen mixture into a chilled large bowl, spooning it.
With a mixer at high speed, beat until fluffy.
Return mixture to the baking pan and freeze until firm, about 1½ hours.
Serve
To serve, remove watermelon ice from the freezer and let it stand at room temperature for 10 minutes for easier scooping.

Shared aroma: 2-nonenal (fatty, green).
Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Watermelon
- Provides the main fruit flavour and most of the liquid that turns into ice crystals.
- Confectioners' sugar
- Adds sweetness and softens the icy texture by lowering the freezing point.
- Lemon juice
- Adds acidity that brightens the watermelon flavour.
The step that matters
Beat the partially frozen mixture until fluffy. Beating breaks up large ice crystals while the mixture is partly frozen, giving a smoother, lighter texture. If it is too firm or too soft at this point, the beating will not work well.
