Why it works: Walnut and butter are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 6,832 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓

Ingredients
Directions

Gradually add the water while stirring.
Once it begins to boil, pour the mixture back and forth between the saucepan and a bowl until smooth and frothy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the soup and add richness by setting as they are gently heated.
- Butter
- Adds fat for richness and a smooth mouthfeel.
The step that matters
Pouring back and forth once it begins to boil. Egg yolk proteins set and can curdle if the mixture overheats. Keeping the heat low and moving the mixture between vessels helps it stay smooth and frothy.
Swap the walnut
How well each one fits the dish's main ingredients (egg, butter, sugar):
- Almondfits better
- Pecansfits better

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