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 ↓
Spanish Stew
Ingredients
Directions
Prepare
Clean and joint the chicken, then fry until browned.
Shred the peppers, removing the seeds, and slice the tomatoes, onion, and garlic.
Make the stew
Place the chicken in a kettle with the tomatoes, peppers, and onion, then add the boiling water.
Cover the kettle and simmer until the chicken is tender.
Remove the chicken, strain the remaining contents, and rub the vegetables through a sieve.
Return the vegetable puree to the kettle, add the peas, mushrooms, grated potatoes, and salt.
Cook until the potatoes are tender, then add the chicken back in and heat thoroughly.
Serve
Serve with a border of mashed potatoes or boiled rice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken
- Provides the main protein, and frying first browns the surface for flavor.
- Tomatoes
- Add acidity and body, and break down into the puree that thickens the stew.
- Red peppers
- Contribute sweetness and aroma, and their flesh breaks down into the sieved base.
- Potatoes
- Grated potatoes release starch that thickens the stew as they cook.
- Onion
- Adds savory aromatic depth as it softens into the vegetable base.
The step that matters
Rub the vegetables through a sieve. Pressing the cooked tomatoes, peppers, and onion through a sieve forms a smooth puree; skipping or rushing this leaves coarse pieces and a thinner, uneven stew.
Swap the clove
How well each one fits the dish's main ingredients (chicken, tomato, pepper, peas, mushroom, potato, onion):
- Garlicfits better

Fit is the average pairing score against chicken, tomato, pepper, peas, mushroom, potato, onion. Candidates are from the same food group and used in at least 100 recipes.
