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

What each ingredient does

Eggs
Provide the structure and thickening that give the sauce its body.
Sugar
Adds sweetness and helps balance the richness of the eggs.
Butter
Adds richness and a smooth, silky mouthfeel to the sauce.
Wine or vanilla
Adds aroma and flavor to the sauce.

The step that matters

Stir constantly over the water. Gentle, continuous stirring spreads the heat evenly so the egg proteins thicken smoothly instead of setting in lumps on the bottom of the bowl.

Swap the walnut

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

  1. Almondfits better
  2. Pecansfits about as well
  3. Peasfits about as well
  4. Walnutthe original

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