Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Hashed Beef on Toast
Ingredients
Directions
Prepare the beef
Season the chopped cold roast beef with pepper and salt.
For each pint of meat, add 1 tablespoon of flour and stir well.
Add ½ cup of soup stock or water to the mixture.
Cook and toast
Put the mixture into a small stew pan, cover it, and simmer for 20 minutes.
Toast 6 slices of bread until nicely browned.
Serve
After 20 minutes, spread the beef mixture on the toasted bread.
Serve immediately on a hot dish.
If using water instead of soup stock, add 1 tablespoon of butter just before spreading the beef.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main meaty flavor and the chopped texture of the topping.
- Flour
- Thickens the cooking liquid into a light gravy as the mixture simmers.
- Soup stock
- Adds savory liquid that keeps the beef moist while it simmers.
- Butter
- Adds fat and richness when water replaces the stock.
- Bread
- Forms a browned base whose crispness contrasts with the soft beef.
The step that matters
Stirring in the flour. Stir the flour thoroughly into the meat so it disperses evenly. Starch only thickens once it is wet and heated, so unmixed pockets of flour can stay dry and form lumps in the gravy.
