Why it works: Peas and lettuce match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 1,293 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Add body and sweetness, thickening the broth as they break down slightly.
- Lettuce
- Contributes moisture and a mild, tender vegetable flavour to the stew.
- Onions
- Add savoury sweetness and aroma to the broth as they soften.
- Beef or ham bone
- Releases flavour and gelatin into the stewing liquid, enriching the broth.
- Mutton or lamb steaks
- Provide the main meat; browning first adds savoury, roasted flavour to the dish.
The step that matters
Fry the mutton or lamb steaks until nicely browned. Browning triggers the Maillard reaction, which builds deep savoury flavour. Steaks that are pale or steamed in the pan lack this flavour, and the stew tastes flatter.

Fit is the average pairing score against peas, onion, beef, mutton. Candidates are from the same food group and used in at least 100 recipes.
