Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the butter and stock mixture into a smooth, sauce-like base.
- Butter
- Adds richness and carries flavour, and forms the base for the flour roux.
- White stock
- Supplies the liquid that the roux thickens into the sauce.
- Milk
- Adds body and mild sweetness to the sauce.
- Sweet cream
- Adds fat and a smoother, richer texture to the finished sauce.
- Grated horseradish
- Provides the sharp, pungent heat that defines the sauce.
The step that matters
Heat gently without boiling. Boiling can cause a cream-based sauce to separate or turn grainy, and the horseradish's pungent flavour fades with prolonged heat, so gentle warming keeps the sauce smooth and flavourful.
Swap the horseradish

Fit is the average pairing score against butter, flour, milk, cream. Candidates are from the same food group and used in at least 100 recipes.
