Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the meat that becomes tender and rich as it cooks slowly in the sealed bag.
- Onions
- Soften and turn sweet as they cook, adding body and flavour to the stew.
- Potatoes
- Absorb the cooking juices and thicken the stew as their starch softens.
- Cold water
- Adds moisture so the sealed bag steams the ingredients rather than drying them out.
The step that matters
Sealing the bag. A tightly sealed bag traps steam, so the mutton and vegetables cook in their own moisture. A loose seal lets steam escape and can leave the meat dry and tough.
Swap the onion
How well each one fits the dish's main ingredients (mutton, pepper, potato):
- Carrotfits better
- Capsicumfits better
- Tomatofits about as well
- Onionthe original
Fit is the average pairing score against mutton, pepper, potato. Candidates are from the same food group and used in at least 100 recipes.
