Why it works: Walnut and shallot match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 440 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Hashing and Mincing Beef
Ingredients
Directions
Prepare the beef
Place the sliced beef in a stewpan with pickle slices and either walnuts or onions.
Make the sauce
In a separate pan, melt fresh butter and sauté chopped shallots or onions until nearly done.
Add 1 pint of veal stock or gravy and a little ketchup to the sautéed mixture.
Boil for 10 minutes, then season with Cayenne pepper and coarse sea salt.
Stew and serve
Strain the sauce over the beef and let it stew gently until thoroughly hot.
Add a small quantity of browning before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Thinly sliced beef
- Forms the body of the hash, becoming tender as it stews in the sauce.
- Fresh butter
- Fat that softens the shallots or onions and carries their flavour into the sauce.
- Veal stock or gravy
- Liquid base that gives the sauce its body and savoury depth.
- Chopped shallots or onions
- Sweetness and aromatic flavour once softened in butter.
- Ketchup
- Adds sweetness and acidity to the sauce.
The step that matters
Stew gently after straining the sauce over the beef. Boiling hard at this stage can toughen the beef and make the sauce reduce or break unevenly. A gentle stew heats the meat through while keeping it tender and the sauce smooth.
