Ingredients

Directions

Prepare the pastry

  1. Preheat the oven to 325°F and grease the tart pans.

  2. Cut the lard.

  3. Sift the flour into a large bowl using a sifter.

  4. Work the lard and butter into the flour with the tips of your fingers until the mixture resembles coarse breadcrumbs.

  5. Continue kneading, adding the hot water.

  6. Roll the dough into a large ball, cover with wax paper, and refrigerate while preparing the custard filling.

Make the custard filling

  1. Lightly beat the eggs, taking care not to produce any air bubbles.

  2. Stir in the milk and the sugar.

  3. Add the yellow food coloring if using.

Shape and bake

  1. On a large, lightly floured surface, roll out the dough until it is very thin (about 1/8 inch or 3 to 4 mm thick).

  2. Cut the dough in half before rolling out if needed.

  3. Use a pastry cutter to cut out 18 circles that are 3 inches in diameter.

  4. Fit the circles into the tart shells.

  5. Pour the filling into the shells.

  6. Bake until the custard is cooked and a knife inserted in the middle comes out clean (about 35 minutes).

  7. Cool.

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

What each ingredient does

All purpose flour
Forms the structure of the pastry dough.
Lard
Makes the pastry short and tender by coating flour particles with fat.
Butter
Adds flavor and helps the pastry brown while keeping it flaky.
Eggs
Set the custard, giving it its firm, sliceable body.
Whole milk
Provides the liquid and richness that form the custard with the eggs.
Sugar
Sweetens the custard and adds body to the filling.

The step that matters

Beating the eggs gently. Beating eggs hard whips in air bubbles, which can leave holes or a pocked surface in the set custard. Gentle stirring keeps the filling smooth and even.
