Why it works: Butter and bread 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
Make the beef
Season the chopped 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.
Place the mixture in a small saucepan, cover, and simmer for 20 minutes.
Toast and serve
Toast 6 slices of bread until golden brown.
If using water, add 1 tablespoon of butter just before spreading the beef on the toast.
Spread the beef mixture on the toasted bread and 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 is cooked into the hash, giving the dish its main flavour and bulk.
- All-purpose flour
- Thickens the cooking liquid into a gravy that clings to the beef and moistens the toast.
- Soup stock
- Supplies the liquid that simmers with the beef, adding savoury flavour and moisture.
- Butter
- Adds richness and a smooth finish to the water-based hash when it is used in place of stock.
The step that matters
Simmering the beef with flour. Flour must be stirred in well before the liquid is added and the mixture simmers gently, so it thickens evenly without lumps or scorching. Covering the pan keeps moisture in so the beef stays tender rather than drying out.
