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 roux with fat, adding richness and smooth mouthfeel.
- Flour
- Thickens the sauce as the roux cooks with the butter.
- Cream
- Adds fat and body, giving the sauce a rich, smooth texture.
- Chicken stock
- Supplies the liquid base and savory flavor of the sauce.
- Egg yolks
- Enrich and thicken the sauce gently once stirred in off the heat.
The step that matters
Do not let the sauce boil after adding the yolks. Egg yolks contain proteins that scramble and curdle when overheated, leaving the sauce grainy. Keeping it below boiling lets them thicken it smoothly.
