Why it works: Peas and potato are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 1,016 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
- Lamb
- Provides the meat that becomes tender during long, gentle simmering.
- Shelled peas
- Add sweetness and bright color, softening as the stew cooks.
- Butter
- Adds richness and a silky mouthfeel to the stew.
- Flour
- Mixed with butter, it thickens the cooking liquid into a looser sauce.
The step that matters
Mixing the flour with the butter before stirring it in. Flour added directly to hot liquid clumps; blending it with fat first coats each particle so it disperses and thickens smoothly.
Swap the mace
The recipe marks mace as optional. How well each one fits the dish's main ingredients (lamb, peas, butter, flour, pepper, potato):
- Parsleyfits better
- Thymefits better
- Turmericfits better
- Macethe original
Fit is the average pairing score against lamb, peas, butter, flour, pepper, potato. Candidates are from the same food group and used in at least 100 recipes.
