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 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Peel and wash the potatoes, then cut each into eight pieces.
Peel and chop the onions.
Cut the meat into pieces the same size as the potatoes.
Layer and bake
In a deep baking dish, layer potatoes, sprinkle with onions, pepper, and salt, then add a layer of meat.
Repeat layering until the dish is full, finishing with a layer of potatoes.
Grease the top layer of potatoes, pour in the water, and bake at 350°F (175°C) for two hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the dish and become soft and starchy as they bake.
- Beef or preserved mutton
- Provides savory richness and meaty flavor as its juices seep into the layers.
- Onions
- Add aromatic sweetness and savory depth that mellows during baking.
- Water
- Creates steam and moisture so the layers cook through without drying out.
The step that matters
Pouring in the water over the top layer. The water must reach the lower layers to create steam and moisture; if the dish is too dry, the potatoes and meat can scorch or cook unevenly.
