Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Hashed Beef
Ingredients
Directions
Make the gravy
In a stew pan, combine the beef trimmings, bones, onions, potatoes, and sweet herbs.
Add warm water or broth to make the gravy.
Cover and simmer for about 1 hour.
Skim and strain the gravy, removing all fat.
Thicken and finish
In another pot, melt the butter over medium heat.
Stir in the flour and cook for a few minutes.
Add the strained gravy to the pot and bring to a boil.
Stir in the ketchup and the sliced beef.
Simmer for 5 to 10 minutes without boiling.
Serve
Serve in a deep dish with triangular slices of toast dipped in the gravy around the sides.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Roast beef
- Provides the main meat and flavor, cooked gently into the dish.
- Butter
- Adds richness and fat to the gravy, carrying flavor.
- Flour
- Thickens the melted butter and gravy into a smooth, body-rich sauce.
- Potatoes
- Break down during simmering and add body and starch to the gravy.
- Onions
- Soften during simmering, adding sweetness and savory depth to the gravy.
The step that matters
Simmer for 5 to 10 minutes without boiling. Once the beef is added, a gentle simmer keeps the meat tender and ttender-textured. A hard boil toughens meat proteins and can break the flour-thickened sauce, making it grainy or thin.
