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 ↓

Ingredients
Directions
Prepare and boil
Wash the fish and remove bones, then cut into half‑inch pieces.
Pare the potatoes, then place the fish and potatoes in a stew pan.
Cover with boiling water and boil until the potatoes are soft.
Mash and season
Drain the water, then mash and beat the fish and potatoes until very light.
Add the butter and pepper, mixing well.
When slightly cooled, add the beaten egg and more salt if needed.
Fry
Take tablespoonfuls of the mixture and drop them into hot lard to fry until brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt fish
- Provides the salty, savory flavor that defines the dish.
- Potatoes
- Starch gives the mixture bulk and a light, fluffy texture when mashed and beaten.
- Egg
- Binds the mixture so the balls hold their shape while frying.
- Butter
- Adds fat for richness and a smoother, softer mouthfeel.
The step that matters
Frying in hot lard. The fat must be hot enough to set the outside quickly. This forms a browned crust and keeps the balls from soaking up excess grease and turning heavy.
