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

What each ingredient does

Milk
Forms the liquid base of the custard and adds richness and body.
Eggs
Set as the custard cooks, giving it a firm, sliceable structure.
White flour
Thickens the milk when heated, giving the custard its body.
Sugar
Sweetens the custard and balances the flavor.

The step that matters

Boiling the flour mixture for 1 minute. Flour starch only thickens fully once it reaches a boil and is held there, so the minute of boiling cooks out the raw starch taste and sets the thickening before the eggs are added.

Swap the lemon

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

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

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