Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Provide the main flavour and the body of the puree once rubbed through a sieve.
- Butter
- Adds richness and carries flavour as the base for the roux.
- Flour
- Thickens the stock into a smooth sauce when cooked with the butter.
- White stock
- Forms the liquid base that the flour thickens into a sauce.
The step that matters
Stir in the stock gradually after the flour. Adding the stock to the butter and flour roux slowly while stirring keeps lumps from forming, so the sauce thickens smoothly.
Swap the peas
How well each one fits the dish's main ingredients (butter, veal, flour, pepper):
- Almondfits better
- Chestnutfits better
- Walnutfits better
- Peasthe original
Fit is the average pairing score against butter, veal, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
