Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Fish Balls
Ingredients
Directions
Prepare the fish balls
Soak the bread in water, then squeeze out lightly.
In a bowl, mix the soaked bread, halibut, salmon, eggs, cold water, grated onion, pepper, and salt.
Form the mixture into balls.
Cook the balls and gravy
Cook the carrot, onion, celery, and parsley in a little water for about 15 minutes.
Add the fish balls to the pot and boil.
Add the butter and a little sugar, then boil slowly for 1½ hours.
Carefully lift the balls onto a platter.
Stir the gravy into the yolks of 3 eggs and heat until thick, but do not boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Halibut
- Forms the main body of the fish balls, giving them flaky, tender texture.
- Salmon
- Adds richness and fat, keeping the fish balls moist and flavorful.
- Eggs
- Bind the fish mixture so the balls hold their shape while cooking.
- Bread
- Soaked and squeezed, it absorbs moisture and keeps the balls tender.
The step that matters
Stir the gravy into the egg yolks without boiling. Egg yolks thicken through gentle heat; if the mixture boils, the proteins curdle and the sauce turns grainy instead of smooth.
Swap the onion
How well each one fits the dish's main ingredients (salmon, bread, egg, pepper, carrot, celery, parsley):
- Leekfits better
- Parsnipfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against salmon, bread, egg, pepper, carrot, celery, parsley. Candidates are from the same food group and used in at least 100 recipes.
