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

What each ingredient does

Egg
Its proteins set when heated, helping to thicken the milk.
Flour
Its starch swells in hot liquid and thickens the mixture.
Milk
Forms the main liquid and gives the dish its creamy body.
Sugar
Adds sweetness to taste.

The step that matters

Adding the egg and flour mixture to the boiling milk. Egg proteins and starch can clump or curdle if they meet very hot milk unevenly. Blending them smooth with cold milk first and stirring while adding helps the starch disperse and the custard thicken evenly.

Swap the nutmeg

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

  1. Cinnamonfits better
  2. Nutmegthe original
  3. Jalapenofits less well
  4. Turmericfits less well

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