Why it works: Sage and marjoram match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 507 recipes. Both carry 2-hexenal, which smells green, leafy. The science ↓
Collared Eels
Ingredients
Directions
Prepare the eels
Select the finest eels and do not remove the skin; carefully extract the bone.
Spread out the eels and rub them with chopped sage, parsley, and mixed spices.
Bind the eels tightly with broad white tape.
Cook and pickle
Add a handful of coarse sea salt and bay leaves to boiling water and cook the eels for 45 minutes.
Hang the cooked eels to dry for 12 hours.
In the boiling water used for the eels, add vinegar, whole pepper, and marjoram or thyme, and boil for 12 minutes.
Let the pickle stand for as long as the eels are hung.
Unroll the eels carefully to minimize skin abrasion and place them in the pickle.
Serve
Serve in slices or whole, garnished with parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Firm, oily flesh that holds its shape through long cooking and pickling.
- Vinegar
- Acidity that preserves the eels and gives the pickle its sharp flavour.
- Sage
- Adds a savoury, aromatic herbal flavour to the eels.
- Bay leaves
- Contribute a subtle aromatic flavour to the cooking water.
The step that matters
Unroll the eels carefully after hanging. Cooked eel skin is delicate and tears easily when handled, so unrolling gently keeps the skin intact. Intact skin helps the eels hold their shape and keeps the pickle from breaking down the exposed flesh.
Swap the parsley
