Why it works: Beef and mushroom are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,232 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
Beef Collops
Ingredients
Directions
Prepare
Remove the meat from the tin and cut it into small pieces.
Dredge the meat pieces in flour and fry them in the pan used for the onion.
Make the sauce
In a pot, combine the water, any jelly from the meat, capers, and minced onion fried in butter.
Season with pepper and coarse sea salt.
Thicken the sauce with the remaining butter and flour.
Finish and serve
Once the onion is tender, add the meat and mushroom ketchup, and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ramornie beef
- Provides the main protein, which is cut into pieces and cooked in the sauce.
- Flour
- Coats the meat for browning and thickens the sauce as it cooks.
- Butter
- Fries the onion and meat and adds richness to the sauce.
- Small onion
- Adds savoury sweetness and body to the sauce as it softens.
- Mushroom ketchup
- Adds savoury, umami depth to the sauce.
The step that matters
Thicken the sauce with the butter and flour. Flour needs to be cooked into the fat and liquid so it thickens smoothly without lumps or a raw starchy taste. Stirring as it heats helps the starch swell evenly.
Swap the capers
How well each one fits the dish's main ingredients (beef, butter, flour, onion, mushroom, ketchup, pepper):
- Thymefits better
- Garlicfits better
- Parsleyfits about as well
- Capersthe original
Fit is the average pairing score against beef, butter, flour, onion, mushroom, ketchup, pepper. Candidates are from the same food group and used in at least 100 recipes.
