Why it works: Leek and pepper work together. They rank in the top 12% of all ingredient pairs, and cooks put them together in 965 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Make the soup
Pour the water from the boiled leg of mutton into a stew pot.
Add chopped leeks, pepper, and salt.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leeks
- Provide the main flavour and body of the soup as they soften during simmering.
- Oatmeal
- Thickens the broth as its starch swells and gelatinises when heated.
- Water from boiled leg of mutton
- Serves as the flavourful stock base, carrying meat essence into the soup.
The step that matters
Adding the oatmeal mixture. Oatmeal mixed with water must be smooth before it goes in, otherwise lumps form. Stirring while it simmers gently keeps the starch dispersed and prevents it from scorching on the bottom of the pot.
