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

Sugar
Sweetens the ice and lowers the freezing point so it stays softer.
Gelatin
Sets gently and gives the ice a smoother, less icy texture.
Lemon juice
Adds acidity that balances the sweetness and brightens the flavour.
Pineapple
Adds fruit flavour and some texture from the grated or chopped pieces.

The step that matters

Cool the mixture before freezing. Gelatin needs the syrup to cool enough before it sets properly, and adding lemon juice to a hot mixture can make the flavour and texture uneven. Cooling first helps the ice freeze smoothly.

Swap the lemon

Fit is the average pairing score against sugar, gelatin, pineapple. Candidates are from the same food group and used in at least 100 recipes.
