Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Warmed-Over Meats Hash
Ingredients
Directions
Prepare
Cut away all bone and gristle from the meat.
Chop cold potatoes or mash freshly boiled ones.
Mix the meat and potatoes, season with salt and a little flour.
Cook
Heat lard in a frying pan, add the mixture, and let it brown without stirring.
Once browned, turn it out flat on a platter or fold like an omelet.
Add freshly ground pepper after cooking.
Serve
Serve on triangular pieces of toast if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked meat
- Provides the main savoury body and flavour of the hash.
- Potatoes
- Bind the meat together and add starch that helps form a crisp browned crust.
- Flour
- Lightly coats the mixture and helps it hold together and brown.
- Lard
- Conducts heat and adds fat that promotes browning in the pan.
The step that matters
Let it brown without stirring. Leaving the hash undisturbed lets a crust form on the pan surface through Maillard browning. Stirring keeps moisture and steam in contact with it, so the hash stays soft and pale instead of crisp.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (meat, potato, flour, pepper):
- Spinachfits better
- Capsicumfits better
- Okrafits better
- Onionthe original
Fit is the average pairing score against meat, potato, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
