Why it works: Parsley and potato are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,855 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Fried Fish and Potatoes
Ingredients
Directions
Prepare the fish
Clean the fish, then cut it as needed.
Sprinkle the fish with salt and let it sit for a few minutes.
Wipe the fish dry.
Beat the egg.
Place flour on a plate.
Dip the fish first in flour, then in egg.
Fry the fish
Heat oil in a frying pan gradually.
Fry the fish gently in hot oil until golden brown, about 5 minutes per side.
If the pan isn't deep enough, turn the fish to fry evenly.
Drain the fish on paper after frying.
Arrange the fish on a dish and garnish with fried or raw parsley.
Prepare and fry the potatoes
Wash and peel the potatoes.
Cut the potatoes into thin rounds or slices.
Do not wash the potatoes again.
Rub the potatoes dry.
Fry the potatoes in hot oil until browned.
Drain the potatoes on paper without adding salt.

Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Its firm flesh holds together during gentle frying and cooks through to a flaky texture.
- Egg
- Coats the floured fish, helping the crust bind and brown during frying.
- Flour
- Forms a dry coating that crisps and browns in the hot oil.
- Potatoes
- Starchy slices fry to a golden, crisp exterior while the inside turns tender.
The step that matters
Wipe the fish dry before coating. Surface moisture stops flour and egg from sticking evenly and turns the oil steamy, so the coating can slide off or fry unevenly instead of browning.
Swap the potato
How well each one fits the dish's main ingredients (fish, egg, flour, parsley):
- Shallotfits better
- Chivefits better
- Leekfits better
- Potatothe original
Fit is the average pairing score against fish, egg, flour, parsley. Candidates are from the same food group and used in at least 100 recipes.
