Why it works: Butter and wine are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 8,645 recipes. Both carry 2-furfurylthiol, which smells coffee, roasted. The science ↓

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):
- Almondfits better
- Pecansfits about as well
- Peasfits about as well
- 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.
