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

What each ingredient does

Egg white
Whipped to stiff froth, it forms the airy, floating topping that gives the dish its light texture.
Egg yolk
Thickens the milk custard as it heats, giving it a smooth, rich body.
Milk
Forms the base of the custard, providing liquid and richness.
Flour
Helps stabilise the custard so it thickens without splitting.
Granulated sugar
Sweetens the custard and helps the yolk mixture become creamy.

The step that matters

Stirring the custard for 2 minutes. Egg yolks thicken as they heat, but if the custard gets too hot or is not stirred constantly, the yolk can scramble and curdle. Continuous stirring keeps the heat even so the custard stays smooth.

Swap the lemon

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

  1. Vanillafits better
  2. Raisinfits better
  3. Figfits better
  4. Lemonthe original

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