  1. Put the bones, onions, parsley, mace, anchovies, and stock into a pot.

  2. Boil slowly for 1 hour.

  3. Strain the broth.

  4. Skim off the fat.

  5. Let the broth cool.

Assemble and bake

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):

  1. Thymefits better
  2. Garlicfits better
  3. Marjoramfits better
  4. 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.
