Why it works: Butter and mushroom 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 ↓
Frying Meat
Ingredients
Directions
Prepare
Heat a vegetable dish with a strainer to drain off fat.
Cook the onions and steaks
Fry the onions in dripping until softened, then transfer to the vegetable dish.
In the same pan, fry the steaks in more dripping until cooked, then place them in a hot dish.
Pour off excess fat from the frying pan, then sprinkle flour into the pan and cook until slightly browned.
Make the sauce and serve
Add the walnut-sized butter, water, mushroom ketchup, and pepper to the pan, mixing well.
Once it boils, strain the sauce into the dish with the steaks and serve hot.
Serve the onions either in the vegetable dish or arranged around the steak.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the pan juices into a smooth sauce as it cooks with the fat.
- Butter
- Adds richness and a glossy finish to the sauce.
- Mushroom ketchup
- Adds concentrated savoury, umami flavour to the sauce.
- Onions
- Add sweetness and soft texture as they soften in the fat.
The step that matters
Browning the flour in the fat. Flour must cook in the fat until slightly browned so its starch loses its raw taste and the sauce gains a nutty colour. Stirring keeps it from scorching or lumping before the liquid is added.
