Lemon and sugar 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

Arrowroot
Thickens the liquid as its starch swells in hot water, giving a smooth body.
Lemon juice
Adds acidity that brightens the flavor and sharpens the sweetness.
Sugar
Adds sweetness and lowers the freezing point, keeping the ice softer.
Lemon peel
Adds aromatic lemon oils that give fragrance beyond the juice's sourness.

The step that matters

Pouring the boiling water into the arrowroot. Arrowroot starch must be fully suspended before heating. Adding the boiling water slowly while stirring prevents lumps, because the starch swells and thickens quickly once hot.
