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 ↓

Prepare

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton chops
- Provide the main meat, which becomes tender and flavours the cooking liquid during gentle stewing.
- Potatoes
- Soften during stewing and thicken the gravy as their starch releases into the liquid.
- Onions
- Add savoury flavour and sweetness as they soften into the stew.
- Cold water
- Forms the cooking liquid that gently braises the meat and creates the gravy.
The step that matters
Covering the stewpan tightly. A tight lid traps steam so the liquid cannot evaporate too fast. This keeps the meat moist and lets it become tender through gentle, even cooking.
Swap the potato
How well each one fits the dish's main ingredients (mutton, onion):
- Leekfits about as well
- Potatothe original
- Turnipfits less well
- Chivefits less well
Fit is the average pairing score against mutton, onion. Candidates are from the same food group and used in at least 100 recipes.
