Why it works: Lemon and parsley 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 ↓
Stewed Eels
Ingredients
Directions
Prepare the eels
Skin and cut the eels into 2‑inch pieces.
Place the eels in a pan with the stock, onion, herbs, mace, parsley, lemon juice, and peppercorns.
Bring to a boil, skim, and simmer for 15 minutes.
Remove the eels and let them drain.
Make the sauce and serve
In another pan, melt the butter and stir in the flour until smooth.
Add the liquid from the fish and boil for 5 minutes.
Strain the sauce over the eels arranged in the center of a dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Main protein; poaching in the stock cooks them gently and keeps them moist.
- Butter
- Fat that enriches the sauce and carries flavour.
- Flour
- Thickens the butter and stock into a smooth sauce.
- White stock
- Cooking liquid that flavours the eels and becomes the base of the sauce.
- Cream
- Adds richness and body to the sauce.
The step that matters
Simmer the eels gently after skimming. Boiling hard toughens the delicate flesh and clouds the stock, so the eels should only simmer once the liquid has been brought to a boil and skimmed.
Swap the mace
How well each one fits the dish's main ingredients (cream, lemon, pepper, butter, parsley, onion, flour):
- Thymefits better
- Tarragonfits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against cream, lemon, pepper, butter, parsley, onion, flour. Candidates are from the same food group and used in at least 100 recipes.
