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 ↓
Pot Roast
Ingredients
Directions
Sear the meat
Place the meat skin side down in a pot and sear until browned.
Turn the meat occasionally until the entire surface is browned.
Simmer
Add the bay leaf, onion slices, and boiling water.
Bring to a boil, then reduce heat and simmer slowly.
Cook for 15 to 20 minutes per pound until the meat is tender.
Turn the meat once during cooking.
When halfway done, add salt and pepper.
If the meat is scorching, add a little more boiling water.
At the end, there should be just enough liquid to cover the bottom of the pot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Meat
- Browning in the pot builds flavor, and slow simmering breaks down connective tissue to make it tender.
- Boiling water
- Provides moisture so the meat simmers gently instead of scorching on the pot bottom.
- Onion
- Adds aromatic sweetness and flavor to the cooking liquid as it softens.
The step that matters
Sear the meat until fully browned. Browning creates deep flavor through the Maillard reaction. Pale meat skipped in the pan will taste flat, and the sauce will lack depth.
