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 ↓
Codfish Balls
Ingredients
Directions
Prepare
Soak the codfish in cold water overnight, changing the water at bedtime.
In the morning, boil the potatoes until tender, then mash them with the butter until smooth.
Make the balls
Remove all bones from the codfish and mix it with the mashed potatoes, beating with a fork.
Beat the egg until frothy and mix it into the codfish and potato mixture.
Season with black pepper and coarse sea salt, and form the mixture into small balls.
Fry and serve
Heat lard in a frying pan and fry the balls until they are light brown, about 5 minutes.
Serve immediately on a dish with sprigs of parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Forms the main body of the balls and supplies the savoury flavour.
- Potatoes
- Add starch and softness, binding the fish and keeping the balls moist.
- Butter
- Adds richness and smoothness to the mashed potato.
- Egg
- Binds the mixture so the balls hold their shape while frying.
The step that matters
Forming and frying the balls. The mixture must be well mashed and bone-free and held together by the egg and potato. If it is too wet or loose, the balls can fall apart in the hot lard, so shape them firmly and fry until golden brown.
Swap the potato
