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.
Assemble
Layer the steak or mutton, potatoes, onions, mushrooms, and kidneys in an earthen pot.
Season with salt and pepper.
Pour ketchup over the layers.
Top with oysters and the snipe, if using.
Cover the pot with pastry.
Bake
Bake in a 350°F (175°C) oven for at least 2 hours.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rump steak or mutton
- Provides the meat and rich savoury flavour that the dish is built around.
- Potatoes
- Bulk up the pot and absorb cooking juices, giving a hearty, starchy body.
- Kidneys
- Add a deep, mineral-rich savoury flavour and a tender, slightly firm texture.
- Oysters
- Add a briny, savoury note that seasons the layers as they cook.
- Ketchup
- Adds sweetness, acidity and savoury depth that colours and flavours the layers.
The step that matters
Seal the pastry cover. A tight pastry lid traps steam so the meat and potatoes cook in their own juices and stay moist. Gaps let steam escape, drying the contents and reducing flavour.
Swap the potato
How well each one fits the dish's main ingredients (mutton, onion, mushroom, pepper, ketchup, oyster):
- Shallotfits better
- Capsicumfits better
- Tomatofits about as well
- Potatothe original
Fit is the average pairing score against mutton, onion, mushroom, pepper, ketchup, oyster. Candidates are from the same food group and used in at least 100 recipes.
