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 ↓
Fish Balls
Ingredients
Directions
Prepare
Place the peeled potatoes in a large pan and sprinkle the shredded fish over them.
Cover with boiling water and cook for 30 minutes.
Drain the water and mash the fish and potatoes until fine and light.
Shape and season
Add the butter, salt, pepper, and egg; mix well for 3 minutes.
Shape the mixture into smooth balls about the size of a small egg.
Fry
Heat the Cottolene until smoking hot, then fry the balls until browned, about 5 minutes.
Do not crowd the frying basket; fry 6 to 8 balls at a time.

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 savory flavor and is mashed into the potato to form the body of the ball.
- Potatoes
- Starch bulks out the mixture and gives the balls a light, fluffy texture when mashed.
- Egg
- Binds the mashed mixture so the balls hold their shape while frying.
- Butter
- Adds richness and moisture to the mashed mixture.
The step that matters
Fry in small batches in very hot fat. Frying in fat that is smoking hot browns the outside quickly and seals it, so the balls absorb less grease. Crowding the basket drops the fat temperature, which makes the balls soggy and pale.
Swap the potato
How well each one fits the dish's main ingredients (fish, egg, butter, pepper):
