Why it works: Onion and potato 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Remains of any joint of cold roast mutton
- Provides the main meat filling, already cooked, so it only needs to be heated through.
- Mashed potatoes
- Forms the layers that enclose the filling and add a soft, moist body.
- Onions
- Frying them until light brown adds sweetness and savoury depth to the filling.
- Gravy
- Moistens the minced meat so the filling does not dry out in the oven.
The step that matters
Moistening the filling with gravy. Cooked meat dries out during a long bake, so the gravy must be enough to keep the mutton moist without making the filling watery under the potato layers.
Swap the mace
How well each one fits the dish's main ingredients (mutton, onion, pepper, potato):
- Garlicfits better
- Parsleyfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against mutton, onion, pepper, potato. Candidates are from the same food group and used in at least 100 recipes.
