Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Pot Roast
Ingredients
Directions
Braise the beef
Wash the beef and place it in a pot with enough water to cover it.
Set over low heat and stew for one hour.
Season with salt and pepper, then continue stewing until tender, adding a little onion.
Remove the meat and pour the gravy into a bowl.
Brown and make the gravy
Add a large lump of butter to the pot, dredge the meat with flour, and return it to the pot to brown, turning often to prevent burning.
Skim the fat off the gravy, then pour it back in with the meat.
Thicken the gravy with flour mixed with water and pour it into a gravy dish.
Serve
Serve the meat on a platter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main meat that becomes tender through slow, moist stewing.
- Butter
- Adds fat that helps the floured meat brown in the pot.
- Flour
- Coats the meat to aid browning and thickens the gravy.
- Onion
- Adds aromatic flavor to the stewing liquid and gravy.
The step that matters
Turning the meat while browning. Floured meat can scorch quickly over direct heat, and the flour burns to a bitter taste. Turning often keeps the coating an even golden brown instead of dark and harsh.
