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 ↓
Swiss Steak
Ingredients
Directions
Prepare the steak
Pound flour into the steak until well coated.
Brown both sides of the steak in a skillet with lard and butter.
Simmer
Add sliced onions, sliced tomato, and canned tomatoes on top of the steak.

Cover and let simmer slowly for 2 hours.
One hour before done, sprinkle with pepper and coarse sea salt.
Add more water to the gravy if needed.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Thick round steak
- Tough cut that becomes tender through long, slow, moist cooking.
- Flour
- Coats the steak so it browns well and helps thicken the gravy.
- Lard and butter
- Fat for browning the steak and adding rich flavor.
- Onions
- Add sweetness and aroma as they soften into the gravy.
- Tomatoes
- Add acidity and moisture that build the sauce.
The step that matters
Simmer slowly with the lid on. Low, covered simmering breaks down the tough connective tissue in round steak. Boiling hard or letting the liquid evaporate can leave the meat tough and dry, so the gravy needs enough water.
Swap the tomato
How well each one fits the dish's main ingredients (flour, butter, onion, pepper):
- Chivefits better
- Okrafits better
- Leekfits better
- Tomatothe original
Fit is the average pairing score against flour, butter, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
