Why it works: Syrup and sugar match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 5,842 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

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

Lemon juice
Provides the sharp acidity that defines the flavour of the ice.
Syrup
Adds sweetness and keeps the mixture from freezing rock-hard.
Whites of 3 eggs
Whipped into foam, they add airiness and a light, lifted texture.
Lemon peel
Rubbed onto sugar to release aromatic oils, adding fragrance to the ice.

The step that matters

Fold the whipped egg whites into the partially frozen mixture. The mixture must be only partly set so the whites blend in without deflating. If it is fully frozen, the foam cannot fold through evenly and the ice turns dense and lumpy.

Swap the lemon

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

  1. Vanillafits better
  2. Raisinfits better
  3. Lemonthe original
  4. Figfits about as well

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