Why it works: Parsley and pepper 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 ↓
Fish Pie, with Tench and Eels, and Hard Eggs
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.

Clean the tench.
Skin the eels.
Bone the tench.
Bone the eels.
Cut the eels into 2-inch pieces.
Make the broth
Put the bones, onions, parsley, mace, anchovies, and stock into a pot.
Boil slowly for 1 hour.
Strain the broth.
Skim off the fat.
Let the broth cool.
Assemble and bake
Combine the tench, eels, whole mushrooms, and egg yolks in a dish.
Season with salt, pepper, and chopped parsley.
Pour in some of the cooled broth.
Cover the dish with puff pastry.
Bake at 350°F (175°C) for about 30 minutes.
Wait until the pastry begins to color.
Pour more broth over the pastry.
Brush the top of the pie with egg.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tench
- Forms the flaky fish filling that gives the pie its main body.
- Eels
- Adds rich, firm pieces of fish that hold their shape during baking.
- Hard-boiled egg yolks
- Add richness and a creamy, crumbly texture to the filling.
- Anchovies
- Contribute savory depth to the broth that flavors the pie.
- Stock
- Provides the liquid base of the broth that keeps the filling moist.
The step that matters
Wait until the pastry begins to color. Pouring broth over the pastry too early can make it soggy. Waiting until it starts to brown lets the crust set and color before adding more liquid.
Swap the mace
How well each one fits the dish's main ingredients (onion, parsley, pepper, mushroom, egg):
- Thymefits better
- Garlicfits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against onion, parsley, pepper, mushroom, egg. Candidates are from the same food group and used in at least 100 recipes.
