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 Meat Hash
Ingredients
Directions
Prepare the hash
Chop the leftover meat very fine.
Peel and chop the potatoes to match the quantity of meat.
Dredge the chopped meat and potatoes with coarse sea salt and flour.
Place the mixture in a frying pan with a little water to moisten.
Add butter if the meat is lean.
Cook until heated through.
Add pepper just before serving.
Make the gravy

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leftover cooked meat
- Forms the body of the hash and provides its main savory flavor.
- Potatoes
- Bulk the hash and, once cooked, add starchy body and soft texture.
- Flour
- Coats the pieces and later thickens the gravy by absorbing liquid.
- Butter
- Adds fat and richness, helpful when the meat is lean.
- Salt pork
- Renders fat and savory flavor into the gravy as it browns.
The step that matters
Thicken with flour. Flour must be cooked to remove its raw taste and mixed smoothly into the liquid, or it forms lumps and the gravy stays pasty rather than silky.
