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
- Butter
- Adds richness and a smooth, creamy body to the sauce.
- Sugar
- Sweetens the sauce and helps give it a smooth texture when creamed with butter.
- Egg yolk
- Thickens the sauce gently as it heats and adds richness.
- Wine
- Adds acidity and flavour depth to the sauce.
The step that matters
Heating the egg yolk mixture over low heat. Egg yolks thicken when gently heated but can scramble if the heat is too high. Low heat and steady stirring keep the sauce smooth and prevent curdling.
Swap the nutmeg
How well each one fits the dish's main ingredients (butter, sugar, egg, wine):
- Cinnamonfits better
- Nutmegthe original
- Tarragonfits less well
- Thymefits less well
Fit is the average pairing score against butter, sugar, egg, wine. Candidates are from the same food group and used in at least 100 recipes.
