Why it works: Potato and pork are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,668 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Fish Balls
Ingredients
Directions
Prepare the fish
Soak the fish overnight.
Change the water in the morning and soak again briefly in tepid water.
Cover the fish and heat it gently without boiling for 1–2 hours until cooked.
Chop the cooked fish very finely.
Shape and fry
Mix the chopped fish with mashed potatoes, butter or cream, pepper, mustard, and salt.
Form the mixture into small flat cakes or round balls.
If making balls, dip them in egg and coat with crumbs.
Fry the cakes or balls in the fat from fried pork or in boiling lard until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the mixture and gives the balls their flavour.
- Mashed potatoes
- Bind the chopped fish and add softness to the mixture.
- Butter or rich cream
- Adds moisture and richness so the mixture stays tender.
- Flour
- Forms a dry coating that helps the outside brown during frying.
The step that matters
Heating the fish gently without boiling. Boiling toughens fish proteins and dries them out, making the mixture coarse and less tender. Gentle heat cooks the fish evenly while keeping it moist.
Swap the mustard
The recipe marks mustard as optional. How well each one fits the dish's main ingredients (fish, potato, butter, pepper, flour, pork):
- Capsicumfits better
- Chivefits better
- Asparagusfits better
- Mustardthe original
Fit is the average pairing score against fish, potato, butter, pepper, flour, pork. Candidates are from the same food group and used in at least 100 recipes.
