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

Icing sugar
Provides sweetness and, once dissolved, the body that makes the icing thick and pourable.
Lemon juice
Adds acidity that brightens the sweetness of the icing.

The step that matters

Stir over low heat without boiling. Icing sugar thickens as it warms and can seize or turn grainy if it gets too hot. Gentle heat keeps it smooth and pourable at a thick cream consistency.

Swap the saffron

How well each one fits the dish's main ingredients (sugar, lemon):

  1. Cinnamonfits better
  2. Gingerfits better
  3. Marjoramfits about as well
  4. Saffronthe original

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