Why it works: Mushroom and beef are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,232 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
Beef, Hash, with Croutons
Ingredients
Directions
Make the sauce
Combine stock, lemon pickle, mushroom ketchup, claret, and fried onions in a stewpan.
Heat the mixture over a clear fire until the onions are tender.
Add the beef
Pour the mixture over the sliced cold beef and cover.
Let it stand for 20 minutes.
Move the stewpan closer to the fire, but do not allow it to boil.
Make the croutons and serve
Cut the bread into thin rounds or desired shapes for the croutons.
Fry the bread in boiling butter until golden brown.
Drain the fried bread on a cloth.
Serve the beef hash with the croutons.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold beef
- Provides the main body of the hash, becoming tender as it soaks in the sauce.
- Claret
- Adds acidity and depth of flavour to the sauce.
- Good stock
- Forms the liquid base that moistens and flavours the beef.
- Silver button onions
- Add sweetness and a soft texture to the sauce.
- Bread
- Fries to a golden brown, giving a crisp contrast to the soft hash.
The step that matters
Move the stewpan closer to the fire, but do not allow it to boil.. Boiling a meat mixture toughens the proteins and can make the beef dry and stringy, so gentle heat keeps it tender and juicy.
