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

What each ingredient does

Flour
Thickens the custard as it cooks, giving it body.
Egg yolks
Thicken the custard as they heat and add richness.
Sugar
Sweetens the custard and balances the egg flavor.
Milk
Forms the liquid base that thickens into the custard.

The step that matters

Cook while stirring constantly. Egg yolks and flour can scorch or lump on the bottom of the pan if left unstirred. Constant stirring spreads heat evenly so the custard thickens smoothly.

Swap the vanilla

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

  1. Vanillathe original
  2. Raisinfits about as well
  3. Figfits less well
  4. Blueberryfits less well

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