Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Spanish Steak
Ingredients
Directions
Prepare the meat
Remove bones and trim the steak, using bones for stock.
Sprinkle meat with salt, pepper, and flour, pounding it in with the edge of a saucer.
Cut the steak into pieces for serving.
Brown and simmer
Fry sliced onions in 2 tablespoons of drippings in an iron skillet until brown, then remove from skillet.
Add the remaining 2 tablespoons of drippings and fry the meat on both sides until brown.
Add boiling water to cover the meat, cover tightly, and simmer for about 2 hours, replenishing water and turning as necessary.
At the end of 2 hours, add tomatoes, onions, paprika, and cayenne, and cook until the meat is very tender and the sauce is dark brown.
Serve the meat in the sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Round steak
- Forms the main body of the stew and becomes tender during long, slow simmering.
- Flour
- Coats the meat and thickens the sauce as it browns and cooks.
- Canned tomatoes
- Add acidity and liquid that help build the sauce's flavor and body.
- Onions
- Add sweetness and savory depth as they brown and dissolve into the sauce.
- Drippings
- Provide fat for browning the onions and meat, adding rich flavor.
The step that matters
Browning the meat in drippings. Frying the meat until well browned creates deep flavor through the Maillard reaction. Pale meat gives a flatter, less rich sauce, and the flour coating also needs to brown for good color.
Swap the onion
How well each one fits the dish's main ingredients (tomato, pepper, flour):
- Capsicumfits better
- Okrafits better
- Eggplantfits better
- Onionthe original
Fit is the average pairing score against tomato, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
