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
Chop the cold roast beef finely and season with pepper and coarse sea 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
Put the mixture in a small saucepan, cover, and simmer for 20 minutes.
Meanwhile, toast 6 slices of bread until golden.
Assemble and serve
After 20 minutes, spread the beef mixture on the toasted bread.
If using water instead of soup stock, add 1 tablespoon of butter just before spreading the beef.
Serve immediately on a hot dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold roast beef
- Provides the meat that forms the savoury filling.
- Flour
- Thickens the stock or water into a cohesive, spreadable mixture as it simmers.
- Soup stock or water
- Provides the liquid that moistens the beef and carries the flour as it simmers.
- Butter
- Adds richness and a smooth finish when water replaces the stock.
The step that matters
Simmering with flour. Flour must be stirred in well before simmering so it dissolves evenly; otherwise lumps form and the mixture thickens unevenly.
