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

What each ingredient does

Egg yolks
Thicken the sauce as they set with gentle heat, giving it a rich custard texture.
Sugar
Adds sweetness to balance the sharpness of the lemon juice and wine.
Lemon juice
Adds acidity and bright flavour that cuts through the richness of the yolks.
White wine
Adds aroma and acidity, flavouring the custard while adding liquid.

The step that matters

Remove from heat as soon as it boils. Egg yolks begin to scramble when overheated, which curdles the sauce. Taking it off the heat promptly keeps it smooth and thickened.

Swap the lemon

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

  1. Vanillafits about as well
  2. Lemonthe original
  3. Applefits less well
  4. Plumfits less well

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