Why it works: Onion and potato 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 ↓
Mutton Stew
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
Trim all fat from the mutton and cut it into 1-inch cubes.
In a large bowl, combine the mutton, onions, potatoes, tomatoes, and peas.
Season with pepper and coarse sea salt, then sprinkle with flour and poultry seasoning.
Bag and bake
Place the mixture in a buttered bag and add cold water.
Fold the bag and fasten it securely.
Cook in a moderate oven at 350°F (175°C) for 35 to 40 minutes.
Serve
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Neck of mutton
- Provides the main protein and rich meaty flavor that forms the body of the stew.
- Potatoes
- Absorb cooking juices and soften, thickening the stew and adding body.
- Flour
- Lightly coats the meat and vegetables, helping to thicken the cooking liquid.
- Onions
- Release sweetness and aroma as they cook, building savory depth in the stew.
The step that matters
Sealing the bag. A tightly fastened bag traps steam so the meat and vegetables cook in their own moisture. If it leaks, the liquid evaporates and the stew can dry out and cook unevenly.
Swap the peas
How well each one fits the dish's main ingredients (mutton, onion, potato, tomato, pepper, flour):
- Beansfits better

- Peasthe original
Fit is the average pairing score against mutton, onion, potato, tomato, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
