Why it works: Walnut and lemon match in chemistry and in kitchens. They rank in the top 10% of all ingredient pairs, and cooks put them together in 2,149 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ingredients
Directions
Make the sauce
In a bowl, mix the egg yolk, flour, and cold water.
Pour the boiling water over the mixture and stir well.
Add the piece of butter and sugar, then flavor with lemon juice or nutmeg.
Finish and serve
Beat the egg white until stiff and fold it into the mixture just before serving.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Thickens the sauce and adds richness as it cooks in the hot liquid.
- Flour
- Thickens the sauce by swelling in the liquid to give body.
- Egg white
- Beaten until stiff, it adds lightness and an airy texture to the sauce.
- Sugar
- Adds sweetness that balances the butter and any lemon juice.
- Butter
- Adds fat for smoothness and a rounder, richer mouthfeel.
The step that matters
Pour the boiling water over the mixture and stir well. The egg yolk and flour must be stirred quickly into the hot liquid so the starch and egg proteins thicken evenly without lumps or scrambling.
Swap the walnut
How well each one fits the dish's main ingredients (egg, flour, butter, sugar, lemon):
- Almondfits better
- Pistachiofits better
- Milletfits better
- Walnutthe original
Fit is the average pairing score against egg, flour, butter, sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
