Ingredients: 1 pint of neck or leg of mutton, minced; 2 onions, chopped; 1 lettuce, chopped; 1 pint of green peas; 1 teaspoon of pepper; 4 tablespoons of water; 2 to 3 ounces of clarified butter; cayenne pepper (optional)

Why it works: Lettuce and peas 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

Mutton: Provides the main protein and rich meaty flavor that forms the body of the stew.
Onions: Add sweetness and aroma as they soften during the long simmer.
Green peas: Add bulk, natural sweetness and a soft texture to the stew.
Clarified butter: Adds fat for richness and a smooth mouthfeel.
Lettuce: Softens as it cooks, adding moisture and a mild vegetable body to the stew.
