Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Set the custard into a soft, creamy structure as they cook.
Lemons
Provide the acidity and aroma that flavour the custard, with rind adding fragrant oils.
Warm water
Thins the egg mixture so it can be strained and cooks gently into a smooth custard.

The step that matters

Stir until soft custard. Eggs thicken as they heat, but overheating can curdle them into lumps. Gentle, constant stirring in the hot water bath keeps the custard smooth and evenly set.

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.
