Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

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 salty taste of the balls.
- Potatoes
- Form the soft starchy body that holds the balls together and gives them lightness.
- Egg
- Binds the mixture so the balls hold their shape and set when fried.
- Butter
- Adds richness and fat for a softer, more tender interior.
The step that matters
Beating the mashed mixture until very light. Beating incorporates air and develops a smooth, fluffy texture; under-beating leaves the balls dense, while the potatoes must be soft but not soggy so they mash evenly without becoming wet and loose.
