Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Provide the main protein, which turns firm and flaky when fried.
- Vinegar
- Acidity in the pickle that firms the eel flesh and adds a sharp, tangy flavour.
- Lemon juice
- Adds acidity to the pickle, brightening the flavour of the fish.
- Flour
- Forms a coating that browns in the hot fat and gives the eels a crisp crust.
- Lard or clarified butter
- Frying fat that conducts heat evenly and browns the coating to a golden colour.
The step that matters
Frying the floured eels until golden brown. Fat must be hot enough to crisp the flour coating quickly; if it is too cool, the coating absorbs fat and turns greasy while the eel overcooks.
Swap the onion
How well each one fits the dish's main ingredients (vinegar, lemon, pepper, flour, butter, parsley, marjoram):
