Why it works: Lettuce and cucumber match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,409 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Mutton
Ingredients
Directions
Prepare
Mince the mutton, mixing it with the shredded lettuces, peas, salt, pepper, water, butter, and green onions if using.
Stir the mixture well with a fork over a clear, gentle fire until hot.
Stew
Cover the pot and place it by the side of the stove or on a high trivet to stew gently for 2 hours.
If desired, add cucumbers, mushrooms, curry powder, or onion during the last part of cooking.
Serve
Serve with a dish of boiled rice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the main protein and rich meaty flavour that the stew is built around.
- Butter
- Adds fat and richness, carrying flavour and giving the stew a smooth mouthfeel.
- Young lettuces
- Adds moisture and a soft, tender vegetable texture as they wilt during stewing.
- Young peas
- Adds sweetness and a tender texture to the stew.
The step that matters
Stewing gently with the lid on. Low, gentle heat lets the mince become tender without toughening or drying out. Too much heat can seize the meat and scorch the bottom of the pot.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (mutton, lettuce, peas, pepper, butter, cucumber, mushroom):
- Spinachfits better
- Shallotfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against mutton, lettuce, peas, pepper, butter, cucumber, mushroom. Candidates are from the same food group and used in at least 100 recipes.
