Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. 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 meaty flavor and body as its fat and juices enrich the broth.
- Pearled barley
- Softens during simmering and thickens the stew as its starch releases into the liquid.
- Potatoes
- Break down slightly during cooking, adding body and starch to the stew.
- Onions
- Browning them in meat fat builds savory depth and sweetness in the stew.
The step that matters
Browning the mutton and onions. Searing the meat and onions in its own fat creates browned flavors through the Maillard reaction. Skipping or rushing this step leaves the stew tasting flat and greyish.
Swap the celery
How well each one fits the dish's main ingredients (mutton, potato, barley, onion):
- Garlicfits better
- Thymefits about as well
- Celerythe original
- Parsleyfits about as well
Fit is the average pairing score against mutton, potato, barley, onion. Candidates are from the same food group and used in at least 100 recipes.
