Paste Croustades a LA Financiere

a dozen small Croustade molds

Ingredients

Directions

Make the paste

  1. Rub the butter into the flour until smooth.

  2. Add the salt and egg yolks, then work in enough water to make a soft paste.

  3. Wrap the paste in a cloth and chill it on ice.

  4. Roll out the paste and line a dozen small Croustade molds.

Bake the cases

  1. Fill the molds with flour to hold the paste in place while baking.

  2. Bake until the paste is light brown and crisp.

  3. Remove the flour, brush the insides with egg, and return to the oven for 2-3 minutes.

Fill and serve

  1. In a stewpan, combine the cocks' combs, kernels, mushrooms, foie gras, fowl, and truffles with chicken forcemeat.

  2. Add the Spanish sauce and stir until it coats the spoon.

  3. Fill the baked Croustades with the mixture.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter
Enriches the paste and makes it tender and flaky as it bakes.
Flour
Forms the structure of the paste that holds the case shape.
Egg yolks
Add richness and help bind the paste into a workable dough.
Foie gras
Adds rich, buttery fat that melts into the filling.
Spanish sauce
Binds the filling and gives it body so it coats the spoon.
Chicken forcemeat
Binds the diced meats and gives the filling a soft, cohesive texture.

The step that matters

Bake the cases blind with flour. Filling the molds with flour supports the thin paste so it keeps its shape instead of slumping. Brushing the baked cases with egg and returning them briefly to the oven seals the surface so the filling does not soak in and soften the crust.
