Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Ingredients
Directions
Make the sauce
Put butter in a chafing-dish and melt it.
Add flour to the melted butter and stir.
Pour in the thin cream gradually, stirring continuously.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce and carries the flour, adding richness to the base.
- Flour
- Thickens the butter and cream into a smooth, stable sauce.
- Thin cream
- Adds moisture and richness, giving the sauce a smooth, creamy body.
- Stewed and strained tomatoes
- Provides moisture, acidity and tomato flavour to the sauce.
- Soda
- Neutralises some tomato acidity, mellowing the sauce's sharpness.
- Cheese
- Provides the main flavour and, melted, gives the sauce its characteristic richness.
- Eggs
- Enrich and thicken the sauce as they set gently with the heat.
The step that matters
Adding the eggs and cheese. Once the cheese has melted, the sauce should be served promptly. Eggs can scramble or curdle if overheated, and cheese can turn stringy or oily when held too long or heated too hard.
