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 says “a moderate oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Remove the fat from the meat and cut it into 8 or 10 pieces.
Slice the onions thinly and cut each potato into 3 or 4 pieces.
Assemble and bake
Layer potatoes at the bottom of an earthenware dish, followed by a layer of meat, a few slices of onion, and season with salt and pepper.
Repeat layers until all ingredients are used, with potatoes on top.
Fill the dish ¾ full with cold water, adding more if it appears dry.
Cover with greased paper and bake at 300°F (150°C) for 2 hours.
Serve in the dish it was cooked in.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef
- Provides the meat that becomes tender and savory during the long, gentle bake.
- Potatoes
- Form the base and top layers, absorbing the cooking liquid and becoming soft.
- Onions
- Add aroma and sweetness as they soften slowly in the steam and juices.
The step that matters
Fill the dish with cold water. Enough liquid must remain to create steam and keep the meat and potatoes from drying out during the long bake. Checking for dryness and adding water as needed protects the texture.
Swap the onion
How well each one fits the dish's main ingredients (beef, potato, pepper):
