Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Observations on Dressing Fish
Ingredients
Directions
Prepare
If the fish is not cleaned, clean it thoroughly.
Soak the fish in a mixture of ½ cup coarse sea salt and water for a few hours to remove any muddy smell.
Rinse the fish and dry it well with a clean cloth.
Fry and serve
If frying, wet the fish with an egg and sprinkle the finest bread crumbs over it.
Heat lard or dripping in a pan until boiling hot.
Carefully plunge the fish into the hot fat and fry until light brown.
Remove the fish and place it on blotting paper to absorb excess grease.
Garnish with raw or fried parsley, lemon, and horseradish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Binds the fine bread crumbs to the fish so the coating stays on during frying.
- Finest bread crumbs
- Form a thin crisp coating that browns in the hot fat.
- Lard or dripping
- Hot fat that fries the coating, giving it a golden, crisp surface.
- Coarse sea salt
- Draws out the muddy odour during soaking and seasons the fish.
The step that matters
Plunge the fish into the hot fat. The fat must be boiling hot before the fish goes in. A hot fat sets the coating quickly, so it crisps rather than soaking up grease and falling apart.
Swap the horseradish
How well each one fits the dish's main ingredients (fish, vinegar, egg, bread, parsley, lemon):
- Shallotfits better

- Horseradishthe original
Fit is the average pairing score against fish, vinegar, egg, bread, parsley, lemon. Candidates are from the same food group and used in at least 100 recipes.
