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 savoury flavour and the bulk of the mixture.
- Potatoes
- Adds starch and body, so the mash holds together and stays soft inside.
- Egg
- Binds the mixture so the fritters hold their shape while frying.
- Butter
- Adds richness and moisture to the mashed mixture.
The step that matters
Adding the egg. If the mixture is still hot, the egg can scramble and the mixture can loosen. Letting it cool slightly keeps the egg smooth and helps it bind the mash.
Swap the potato
