Why it works: Pepper and potato 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 ↓
Fish Balls
Ingredients
Directions
Prepare the fish and potatoes
Wash the fish in cold water and break it into small pieces.
Wash and peel the potatoes, then cut them into pieces.
Cook the fish and potatoes together in boiling water until the potatoes are soft.
Drain and shake over the fire until dry.
Make the mixture
Mash the mixture with a wire potato masher.
Add the beaten egg, butter, and pepper to the mash.
Add more salt if needed.
Beat the mixture until light.
Shape and fry
Take spoonfuls of the mixture and mold the spoonfuls slightly.
Slip the molded balls into the hot fat.
Fry for one minute, or until brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Binds the mash together and helps the balls hold their shape.
- Potatoes
- Provide starch and bulk, giving the mash a soft, tender body.
- Butter
- Adds richness and moisture to the mash.
- Fish
- Supplies the main flavour and protein, flaked into the mash.
The step that matters
Drain and dry the fish and potatoes. Excess water makes the mash loose and soggy, so the balls may fall apart or absorb too much oil. Drying over the heat evaporates surface moisture, letting the mixture hold its shape and brown well in the hot fat.
Swap the potato
How well each one fits the dish's main ingredients (butter, pepper, fish, egg):

Fit is the average pairing score against butter, pepper, fish, egg. Candidates are from the same food group and used in at least 100 recipes.
