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

What each ingredient does

Eggs
Thicken the sauce as they set with gentle heat, giving it body.
Cream
Adds richness and a smooth, velvety texture from its fat.
Milk
Provides the liquid base that the eggs thicken.
Lemon juice
Adds acidity that brightens the flavour and balances the richness.

The step that matters

Heating while stirring constantly. Egg proteins set as they warm, so too much heat or too little stirring can scramble the eggs and leave lumps. Gentle, constant stirring keeps the sauce smooth as it thickens.

Swap the lemon

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

  1. Lemonthe original
  2. Vanillafits about as well
  3. Strawberryfits less well
  4. Figfits less well

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