The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

Gelatine
Sets the liquid into a wobbly gel as it cools.
Egg whites
Whipped to stiff peaks, they add a light, airy foam to the gelatine.
Strawberries
Provide the main fruit flavour and colour in the layers.
Sugar
Adds sweetness and balances the tartness of the lemon juice.
Lemon juice
Adds acidity that brightens the strawberry flavour.

The step that matters

Gradually beat in the gelatine mixture. Adding warm gelatine slowly to the whipped whites, a spoonful at a time, tempers the mixture so it blends smoothly. Dumping it in at once can deflate the foam and leave streaks of set gelatine.

Swap the lemon

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

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

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