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 and bind the eels tightly with tape.
Place them in a stewpan with veal stock, lemon pickle, and white wine.
Simmer over low heat until cooked through.
Make the jelly
Remove the eels and skim the liquid to remove fat.
Season the liquid with salt, clear it with eggs, and strain through a tamis cloth.
Boil the liquid gently until it thickens to a strong jelly.
Pour the jelly into a bowl and let it cool.
Serve
Once the eels are cold, remove the tape, trim the ends, and wipe them dry.
Serve the eels with the jelly around them, garnished 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
- Main protein; rolling and binding keeps the shape while it cooks gently in liquid.
- Veal stock
- Supplies gelatin and savoury body, which sets the cooled liquid into a jelly.
- Eggs
- Egg whites collect fine particles as they cook, clearing the cloudy liquid for the jelly.
- Lemon pickle
- Adds sharp acidity and a bright, tangy flavour to the poaching liquid.
- White wine
- Adds acidity and aroma to the poaching liquid as it reduces.
- Parsley
- Contributes fresh, herbal aroma to the seasoning inside the rolled eels.
The step that matters
Clearing the jelly with eggs. Whisked egg whites trap cloudy particles as they heat and rise, so the liquid must be strained gently through cloth. Rushing this leaves the jelly murky and it may not set clear.
Swap the parsley
How well each one fits the dish's main ingredients (pepper, mushroom, veal, lemon, white wine, egg):

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.
