Why it works: Flour and parsley are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 16,675 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Fried Eels
Ingredients
Directions
Prepare
Prepare and wash the eels, then dry them thoroughly.
Dredge the eels lightly in flour.
If large, cut them into pieces about 4 inches long; if small, curl them and leave whole.
Coat and fry
Brush the eels with egg, then dip them into bread crumbs.
Fry the eels in hot fat until golden brown.
Serve
Serve garnished with fried parsley.

Flour and egg 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
- Eels
- The main protein, which the coating and frying are applied to.
- Flour
- Dry first coating that helps the egg wash adhere to the eels.
- Egg
- Wet binder that makes the bread crumbs stick to the eels.
- Bread crumbs
- Outer coating that browns and crisps during frying.
The step that matters
Dry the eels thoroughly before dredging. Surface moisture stops flour and egg from sticking evenly and steams the coating, so it fries less crisp and may splatter in hot fat.
Swap the parsley
How well each one fits the dish's main ingredients (flour, egg, bread):
- Nutmegfits better
- Capersfits better
- Turmericfits about as well
- Parsleythe original
Fit is the average pairing score against flour, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
