Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Canned meat
- Provides the main savory body and protein of the stew.
- Potatoes
- Their starch softens during steaming and gives the stew substance and a hearty texture.
- Onions
- Soften during boiling, adding mild sweetness and aroma to the stew.
The step that matters
Testing the potatoes and onions for tenderness before removing them. Potatoes and onions must be fully tender, checked with a fork, before they are removed. Undercooked starch stays firm and grainy, while the cooking time is only a guide that depends on size and heat.
Swap the onion
How well each one fits the dish's main ingredients (meat, potato, pepper):
- Capsicumfits better
- Carrotfits better
- Asparagusfits about as well
- Onionthe original
Fit is the average pairing score against meat, potato, pepper. Candidates are from the same food group and used in at least 100 recipes.
