Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt fish
- Provides the main body of the dish, which becomes dry and crisp when fried.
- Dripping or fat
- Conducts heat in the skillet and helps the shredded fish brown and crisp.
The step that matters
Frying the shredded fish until dry and crisp. Fish holds a lot of water after boiling. Frying over steady heat lets that moisture evaporate, so the shreds crisp instead of steaming and turning soggy.
Swap the mustard
The recipe marks mustard as optional. How well each one fits the dish's main ingredients (fish, meat, pepper, onion):
- Potatofits better
- Capsicumfits about as well
- Mustardthe original
- Tomatofits about as well
Fit is the average pairing score against fish, meat, pepper, onion. Candidates are from the same food group and used in at least 100 recipes.
