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

What each ingredient does

Egg yolks
Thicken the mixture as they set with gentle heat, giving it a rich, creamy body.
Sugar
Sweetens the cream and helps keep the yolks smooth while they are beaten.
Flour
Stabilizes the custard so it thickens more evenly and resists curdling.
Milk
Forms the liquid base that the yolks and flour thicken into a cream.

The step that matters

Heat without boiling. Egg yolks thicken as they gently set; if the mixture boils, the proteins can curdle and turn grainy, so the bowl should stay below a boil.

Swap the lemon

The recipe marks lemon as optional. How well each one fits the dish's main ingredients (egg, sugar, flour, milk):

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

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