Why it works: Butter and wine are a kitchen classic. They rank in the top 13% of all ingredient pairs, and 8,645 recipes mention both. 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 fat and richness, giving the sauce a smooth, rich body.
- Sugar
- Adds sweetness and, creamed with butter, helps give a light texture.
- Egg yolks
- Thicken the sauce as they heat and add richness.
- Egg whites
- Add lightness and help the sauce set as they cook.
- Wine
- Adds liquid and acidity, with flavour that carries into the sauce.
- Nutmeg
- Adds a warm aroma to the sauce.
The step that matters
Stirring constantly over the double boiler. Egg proteins thicken gently with heat but can clump or scramble if they cook unevenly. Constant stirring spreads the heat evenly and keeps the sauce smooth.
Flavor stand-ins for the nutmeg
How well each one fits the dish's main ingredients (butter, sugar, egg, wine):
- Cinnamonbetter flavor fit
- Nutmegthe original
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. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
