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 meaty flavor and richness, with browning adding savory depth to the stew.
- Pearled barley
- Thickens the broth as its starch releases during long simmering, and stays chewy.
- Potatoes
- Soften during simmering, adding body and starch that helps thicken the stew.
- Onions
- Browned with the meat to add sweetness and savory aroma to the broth.
The step that matters
Browning the mutton and onions. Browning creates flavor through the Maillard reaction. Pale, steamed meat gives a flat, grey-tasting broth, so the pieces need space and enough heat to color well.
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.
