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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leeks
- Give the soup its main flavour and soften into the broth during the long simmer.
- Oatmeal
- Thickens the broth as its starch swells in the hot liquid, giving a heavier body.
- Water from boiled leg of mutton
- Serves as the meaty, savoury stock that the rest of the soup is built on.
The step that matters
Mixing the oatmeal into the soup. Oatmeal stirred in dry or in lumps will clump and scorch on the bottom of the pot. Mixing it smooth with cold water first lets the starch disperse evenly, and stirring during the final simmer prevents sticking and burning.
