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
Cut the mutton into chops, trimming off some of the fat.
Dip the chops in flour and lay them on the bottom of a pie dish.
Bake
Sprinkle chopped onion over the meat, season with salt and pepper, and cover with cold water.
Cook in a 350°F (175°C) oven for 45 minutes.
Peel the potatoes and slice them, then place the slices on top of the meat.
Return to the oven and bake for another 45 minutes, or until the meat and potatoes are cooked, basting frequently.

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 and flavorful during the long, slow bake.
- Flour
- Coats the chops, helping them brown and thickening the liquid around the meat.
- Potatoes
- Form a starchy top layer that absorbs the cooking juices and becomes soft.
- Onion
- Adds savory aroma and sweetness as it softens into the cooking liquid.
The step that matters
Basting during the second bake. Basting the meat and potatoes with the juices keeps the surface moist and helps the top brown evenly while the meat cooks through.
Swap the onion
How well each one fits the dish's main ingredients (mutton, flour, potato, pepper):
