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 that the other ingredients thicken and flavour.
Egg yolks
Thicken the sauce as their proteins set with gentle heat, adding richness.
Flour
Thickens the sauce by swelling in the hot liquid and adding body.
Egg whites
Whipped to stiff peaks, they add a light, airy texture to the sauce.
Sugar
Adds sweetness and helps balance the richness of the milk and yolks.

The step that matters

Stir in the egg yolks off the heat. Egg yolks set at around 70°C and can scramble into lumps if they meet direct heat while hot. Removing the pan from the heat before stirring them in keeps the sauce smooth and lets it thicken gently.

Swap the vanilla

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

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

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