Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Eel Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the eels
Remove the skin, heads, tails, and fins from the eels, then clean them.
Cut the eels into pieces and place them in a pie dish, seasoning with pepper and salt.
Make the gravy
Make a gravy by boiling the heads, tails, and fins in water with pepper and salt for 30 minutes.
Strain the gravy, let it cool, then thicken it with flour.
Pour the gravy over the eel pieces in the pie dish.
Bake
Cover the dish and bake at 350°F (175°C) for about 1 hour.

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 and flaky as the pie bakes.
- Flour
- Thickens the cooled gravy so it clings to the eel pieces rather than running off.
- Water
- Serves as the base for the gravy, extracting flavour from the heads, tails, and fins.
The step that matters
Thicken the gravy after straining and cooling. Flour thickens liquid only when it is mixed in well and the gravy is cooled enough to hold it. Adding flour to hot or unstrained liquid can clump or leave the gravy thin, so the sauce will not coat the eels properly.
Swap the parsley
How well each one fits the dish's main ingredients (flour, pepper):
- Jalapenofits better
- Turmericfits better
- Parsleythe original
- Marjoramfits about as well
Fit is the average pairing score against flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
