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 meat flavor and, as it simmers, becomes tender and richly savory.
- Pearled barley
- Swells as it cooks, thickening the broth and giving the stew body and chew.
- Potatoes
- Soften during simmering, adding starch that further thickens the broth and makes the stew heartier.
- Onions
- Browning them with the meat builds sweetness and depth in the base of the stew.
The step that matters
Browning the mutton with the onions. Browning creates Maillard reactions on the meat and sugars in the onions, producing deep savory, roasted flavors that a pale, steamed start cannot replicate. Brown in batches if needed so the pieces sear rather than steam.
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.
