Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Stewed Mutton
Ingredients
Directions
Prepare the mutton
Wipe the mutton with a damp cloth and remove the pink skin, bone splinters, and excess fat.
Place the mutton in a granite stew pan and cover with boiling water.
Stew
Cook slowly until the meat is tender, about 1 hour, adding the onion after the first hour.
Add salt and pepper, replenishing boiling water as needed.
When the bones slip out easily, remove from heat and let cool.
Skim and finish
Once the fat hardens, remove it completely.
Return the meat to heat, adding water if the broth is too strong, and adjust seasoning if desired.
When boiling, add tapioca and cook for 10 minutes longer before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the meat that becomes tender and rich-flavoured during slow stewing.
- Onion
- Adds aromatic sweetness and savoury depth to the broth as it cooks.
- Tapioca
- Thickens the hot broth as its starch swells and gelatinizes during final cooking.
The step that matters
Cooking the tapioca. Tapioca must boil in the broth to fully swell and thicken it. Adding it too early or cooking it too briefly can leave the broth thin or the starch grainy.
