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 ↓
Hot Pot
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Remove the meat from the neck of mutton, keeping it in shape.
Set aside the bones for soup.
Assemble and bake
Line a deep casserole dish with a layer of parboiled potatoes and sliced onion.
Place half the meat on top, add another layer of onion and potato, then the remaining meat seasoned with salt, pepper, and curry powder.
Pour in ½ pint of stock and top with whole potatoes.
Cover the dish and bake at 350°F (175°C) until the top layer of potatoes is thoroughly cooked, adding more stock if needed.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the main meat, which becomes tender through slow, covered baking.
- Potatoes
- Form the layers and top, absorbing stock and softening into a moist, starchy base.
- Stock
- Supplies moisture so the dish braises rather than dries out during baking.
- Onion
- Adds savory sweetness and aroma as it softens between the layers.
The step that matters
Adding more stock if needed. The covered dish relies on enough liquid to braise the meat and cook the potatoes; too little stock lets the top dry and the dish scorch before the potatoes are fully cooked.
Swap the onion
How well each one fits the dish's main ingredients (mutton, pepper, potato):
- Carrotfits better
- Capsicumfits better
- Tomatofits about as well
- Onionthe original
Fit is the average pairing score against mutton, pepper, potato. Candidates are from the same food group and used in at least 100 recipes.
