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 ↓
Collared Eels
Ingredients
Directions
Prepare the eels
Lay the eels flat and season with parsley, eschalot, pepper, salt, beaten spices, and mushroom powder.
Roll the eels tightly and bind with tape.
Place in a stewpan with veal stock, lemon pickle, and white wine.
Simmer until cooked through.
Remove from heat and place on a dish.
Make the jelly
Skim fat from the cooking liquid, season with salt, and clear it with the eggs.
Strain through a tamis cloth and boil down until it forms a strong jelly.
Pour the jelly into a basin and let it cool.
Finish and serve
Once cooled, remove the tape, trim the ends, and wipe the eels dry.
Serve with the jelly around the eels, topped with pickled barberries and lemon slices.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Form the main body of the dish, becoming tender as they simmer through.
- Veal stock
- Supplies the liquid that cooks the eels and, reduced, becomes the savoury jelly.
- Eggs
- Clarify the cooking liquid, collecting impurities so the jelly turns clear.
- Lemon pickle
- Adds sharp, acidic flavour that cuts the richness of the eels and stock.
- White wine
- Adds acidity and aroma to the cooking liquid, deepening the flavour of the jelly.
The step that matters
Boiling down the jelly. The liquid must reduce until it sets firmly when cool. Too little reduction leaves a loose jelly that will not hold around the eels, while careful skimming and clarifying keep it clear and free of fat.
Swap the parsley
How well each one fits the dish's main ingredients (pepper, mushroom, veal, lemon, white wine, egg):

- Tarragonfits about as well
Fit is the average pairing score against pepper, mushroom, veal, lemon, white wine, egg. Candidates are from the same food group and used in at least 100 recipes.
