Why it works: Marjoram and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 2,225 recipes. Both carry terpineol, which smells pine, woody. The science ↓
To Collar Eels
Ingredients
Directions
Prepare the eels
Remove the bones, heads, and tails from the eels and lay them flat.
Season the eels with nutmeg, lemon peel, salt, pepper, parsley, marjoram, thyme, savory, and sage.
Roll the eels tightly and bind them with kitchen twine.
Make the poaching liquid
In a pot, boil the heads, tails, and bones in water, vinegar, onion, bay leaves, salt, and pepper.
Once boiling, add the eels and cook until tender.
Remove the eels and continue boiling the liquid until slightly reduced.
Strain and skim the liquid, then let it cool before adding the eels.
Preserve
To preserve, occasionally reheat the liquid and add fresh vinegar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Provide the main body of the dish, firm flesh that holds its rolled shape when cooked.
- Vinegar
- Adds acidity that firms the eel flesh and helps preserve the jellied liquid.
- Lemon peel
- Adds aromatic citrus oils that brighten the rich flavour of the eels.
- Sage leaves
- Contributes a savory, herbal aroma that complements the fish.
The step that matters
Let the liquid cool before adding the eels. Adding eels to hot liquid can cook them further and make them break apart, so cooling the strained liquid keeps the rolls intact and the flesh tender.
Swap the nutmeg
How well each one fits the dish's main ingredients (lemon, pepper, parsley, marjoram, thyme, sage, vinegar):
- Rosemaryfits better
