Why it works: Thyme and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Fish Pie, with Tench and Eels, and Hard Eggs
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the stock
In a stewpan, combine the bones of the tench and eels, onions, thyme, parsley, mace, anchovies, and stock or water.
Bring to a boil over low heat for 1 hour, then strain and skim the fat.
Cool the liquid, then place the tench and eels in a dish.
Assemble the pie
Season with pepper, coarse sea salt, chopped parsley, and add whole mushrooms and egg yolks.
Pour some of the strained liquid over the fish.
Roll out puff pastry and place it around the edge of the dish, covering it.
Before baking, brush the top of the pie with egg.
Bake and serve
Bake in a preheated oven at 400°F (200°C) for about 30 minutes.
When the pastry begins to color, pour some liquid over it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tench
- Forms the flaky, meaty body of the pie filling.
- Eels
- Adds rich, firm pieces that hold their texture during baking.
- Puff pastry
- Forms a crisp, layered crust that rises and browns in the oven.
- Egg yolks
- Enrich the filling and help the glazed top brown.
- Anchovies
- Add savory depth to the stock, rounding out its flavor.
The step that matters
Cool the liquid before assembling. Adding the stock to the fish while it is still hot can overcook the delicate flesh and make the filling watery; cooling it first keeps the fish tender and the pastry crust from becoming soggy.
Swap the mace
How well each one fits the dish's main ingredients (onion, thyme, parsley, pepper, mushroom, egg):
