Why it works: Pepper and onion are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
To Fry Meat
Ingredients
Directions
Prepare
Heat a pan on the fire for a minute and wipe it clean.
When the pan is hot, add fat or butter.
Cook the meat
Add the meat and turn it several times to cook evenly.
Season with salt and pepper per pound of meat.
Make the sauce
In the remaining fat, add onions and flour, then stir in water and vinegar.
Optionally, add chopped pickles for extra flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Meat
- Is the main component that is cooked and browned in the hot fat.
- Flour
- Thickens the pan juices into a sauce as it cooks in the fat.
- Vinegar
- Adds acidity that sharpens the flavor of the sauce.
- Onions
- Add sweetness and aroma as they cook down in the fat.
- Chopped pickles
- Add sharp, acidic flavor to the finished dish.
The step that matters
Adding flour to the fat. Flour must cook briefly in the fat before liquid is added. Stirring it into the hot fat coats the particles so they blend smoothly and thicken the sauce without lumps.
Swap the onion
How well each one fits the dish's main ingredients (butter, meat, pepper, flour, vinegar):
- Shallotfits better
- Mustardfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against butter, meat, pepper, flour, vinegar. Candidates are from the same food group and used in at least 100 recipes.
