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 ↓
Eel Pie
Ingredients
Directions
The book says “a brisk oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Cut the eels into 2-3 inch pieces, removing heads, tails, and fins.
Boil the eels with lemon peel, shallot, mace, and broth until covered.
Make the sauce
Thicken the broth with butter and flour, then add lemon juice.
Strain the mixture and let it cool, then pour over the eels in a pie dish.
Bake
Sprinkle with pepper, salt, and parsley, then cover with puff pastry.
Bake in a preheated oven at 350°F (175°C) for about 1 hour and 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Provide the main protein, which becomes tender as they simmer in the broth.
- Flour
- Thickens the broth into a smooth sauce that coats the eels.
- Butter
- Adds richness and helps bind the flour into the thickened broth.
- Puff pastry
- Forms a crisp, golden crust that seals the pie and browns in the oven.
- Lemon juice
- Adds acidity that brightens the rich broth and sauce.
The step that matters
Thicken the broth with butter and flour. Cooking flour in butter first, then whisking in the broth, prevents lumps and gives a smooth, stable sauce. Adding the lemon juice afterward keeps its bright flavor intact.
Swap the mace
How well each one fits the dish's main ingredients (shallot, lemon, veal, butter, flour, pepper, parsley):
- Capersfits better
- Tarragonfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against shallot, lemon, veal, butter, flour, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
