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 ↓
Lamb Stew
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
In a pot, brown the lamb pieces over medium heat.
Add the chopped onion and cook until translucent.
Stir in the diced potatoes.
Cover with water and season with salt and pepper.
Simmer
Simmer until the lamb is tender and the potatoes are cooked through, about 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb
- Browning gives savory flavor, and slow simmering turns the tough meat tender.
- Potatoes
- Starch thickens the broth slightly and gives the stew body as they cook through.
- Onion
- Cooking until translucent softens its sharpness and adds sweetness to the broth.
The step that matters
Browning the lamb. Searing the meat over medium heat creates browned flavor through the Maillard reaction. Crowding the pot or skipping the sear leaves the meat gray and the stew flatter in taste.
Swap the onion
How well each one fits the dish's main ingredients (lamb, potato, pepper):
- Spinachfits better
- Asparagusfits better

- Onionthe original
Fit is the average pairing score against lamb, potato, pepper. Candidates are from the same food group and used in at least 100 recipes.
