Why it works: Mushroom and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 12,525 recipes. Both carry trans-2-decenal, which smells waxy, orange. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal
- Provides the meat, which is gently reheated in the sauce rather than cooked through.
- Flour
- Thickens the butter and onion mixture into a roux that gives the sauce body.
- Egg yolks
- Enrich and thicken the sauce, adding richness and a smooth, silky texture.
- Mushrooms
- Add earthy flavour and moisture to the sauce.
- Veal stock
- Forms the liquid base of the sauce, carrying savoury flavour.
The step that matters
Adding the egg yolks. Egg yolks thicken through gentle heat. If the sauce is too hot or the yolks are added too quickly, they can scramble and turn grainy, so add them slowly and keep the heat low.
Swap the onion
How well each one fits the dish's main ingredients (veal, mushroom, egg, butter, flour):

- Chivefits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against veal, mushroom, egg, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
