Why it works: Onion and pepper 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 ↓
Stewed Beefsteaks
Ingredients
Directions
Make the gravy
Heat a stew pan over low heat.
Add the steak with 2 tablespoons of butter. Cook the steak until the butter forms a white gravy.
Pour the gravy into a bowl.
Add more butter to the steak. Cook until done.
Stew and serve
Return the gravy to the pan.
Fry the steak. Add the steak back to the gravy.
Stir in 1 tablespoon of wine and the sliced onion. Stew for 10 minutes.
Alternatively, fry the steak slightly.
Add ½ cup of water, onion, walnut ketchup, pepper, and salt. Cover and simmer until cooked.
Thicken with flour.
Serve hot.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Steak
- Provides the meat that is browned and then stewed until tender.
- Butter
- Fries the steak and forms the white gravy that becomes the base of the sauce.
- Onion
- Adds savory sweetness and aroma as it softens in the stew.
- Flour
- Thickens the cooking liquid into a smoother, heavier sauce.
- Walnut ketchup
- Adds a dark, savory, tangy flavor to the sauce.
The step that matters
Cook the steak until the butter forms a white gravy. Butter that is heated too hard browns and turns bitter, while gentle heat lets its milk solids and fat separate into a pale, flavorful gravy. Overheating spoils the base of the sauce.
Swap the onion
How well each one fits the dish's main ingredients (butter, walnut, ketchup, pepper, flour):
- Shallotfits better
- Capsicumfits better
- Horseradishfits better
- Onionthe original
Fit is the average pairing score against butter, walnut, ketchup, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
