Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken
- Gives the stew its main protein and rich meaty flavor as it simmers in the broth.
- Tomatoes
- Add acidity and body, and their pulp thickens the stew once sieved.
- Potatoes
- Grated potatoes thicken the broth and add starch for a fuller texture.
- Red peppers
- Add sweetness and fresh pepper flavor to the stew base.
- Onion
- Adds savory depth and aroma to the broth.
The step that matters
Rub the vegetable mixture through a sieve. Pressing the cooked tomatoes, peppers, and onion through a sieve breaks them down into a smooth, thickened base. Skipping or rushing this leaves the stew thin and chunky.
Swap the peas
How well each one fits the dish's main ingredients (onion, chicken, tomato, pepper, mushroom, potato):
- Beansfits better
- Sesamefits better
- Chickpeafits better
- Peasthe original
