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
- Adds fat and richness, and forms the base of the roux with the flour.
- Flour
- Starch that thickens the liquid into a smooth, pourable sauce.
- Chicken stock
- Forms the main liquid of the sauce and carries its savoury flavour.
- Cream
- Adds moisture and richness, giving the sauce a smoother mouthfeel.
- Egg yolk
- Enriches and further thickens the sauce as its proteins set gently with heat.
The step that matters
Add the stock and cream gradually while stirring constantly. Flour starch must be spread evenly through the liquid. Adding the liquid slowly while stirring keeps the starch granules from clumping as they swell, so the sauce stays smooth instead of lumpy.
