Why it works: Onion and horseradish match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 1,784 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Steaks
Ingredients
Directions
Cook the steaks
Cut the steaks thinner than for broiling.
Heat butter or clarified dripping in an iron frying pan until hot.
Add the steaks and turn them until cooked to your liking.
Remove the steaks from the pan, keeping 1 tablespoon of fat.
Make the catsup sauce
Stir in flour to make a paste and cook until slightly brown.
Add boiling water to reach the thickness of good cream.
Stir in catsup or pickle and boil for a few minutes.
Strain the sauce over the steaks.
Optional: Add sliced onion or minced shallot and port wine to the sauce.
Garnish with horseradish or pickles.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Steaks
- The main protein, cooked in hot fat until done to the cook's preference.
- Flour
- Stirred into the hot fat to form a paste that thickens the sauce.
- Catsup
- Adds savory, tangy flavour to the sauce.
- Butter or dripping
- Fat for searing the steaks and the base for the sauce.
The step that matters
Browning the flour paste. Cooking the flour in the fat until slightly brown develops a nutty flavour and removes raw starch taste. Adding boiling water to an undercooked paste can leave the sauce pasty and floury.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (butter, flour, mushroom, horseradish, walnut):
- Shallotfits better
- Beetrootfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against butter, flour, mushroom, horseradish, walnut. Candidates are from the same food group and used in at least 100 recipes.
