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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce with fat and gives it a smooth, rich body.
- Flour
- Thickens the melted butter and water into a stable base for the sauce.
- Thick cream
- Adds richness and a smooth, velvety texture.
- Anchovy
- Adds a savory, salty depth of flavor in small amounts.
- Lemon juice
- Adds acidity that brightens the rich sauce.
The step that matters
Stir in the lemon juice carefully. Acid can cause dairy proteins in cream to curdle when heated, so stirring well while adding the lemon helps keep the sauce smooth.
