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
Skin the eels, cut off the heads, tails, and fins, and clean the eels.
Cut the eels into pieces.
Place the eel pieces in a pie dish.
Season the eel pieces with pepper and salt.
Make the gravy
Boil the heads, tails, and fins in water with pepper and salt for 30 minutes.
Strain the gravy.
Let the gravy cool.
Thicken the gravy with flour.
Bake and serve
Pour the gravy over the eel pieces.
Cover the pie.
Bake the pie for about 1 hour at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Provide the main meat, which becomes tender during the long baking.
- Flour
- Thickens the cooled gravy so it clings to the eel pieces rather than running off.
- Water
- Forms the base of the gravy, extracting flavour from the boiled heads, tails, and fins.
The step that matters
Let the gravy cool before thickening it. Flour added to very hot liquid can clump instead of dissolving smoothly. Cooling the strained gravy first lets the flour disperse evenly and thicken into a smooth sauce.
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.
