Preparation
Toast the flour in a pot, stirring constantly, until it turns a light golden color.
In another pot, toast the ground almonds, also stirring constantly.
Sift the flour.
Sift the powdered sugar.

Making the dough
Mix the lard (at room temperature) with the powdered sugar (do not melt the lard). Once well mixed, it should form a white paste.

Add the flour (mixed with cinnamon and salt) and the toasted ground almonds. Knead well until you have a smooth, even dough.

Preheat the oven to 400°F (200°C) using the broil setting (top heat only).

Roll out the dough with a rolling pin to about 3/4 inch thick (2 cm).

Use a round cutter to shape the cookies.

Place the portions on a baking sheet lined with parchment paper. Optionally, sprinkle sesame seeds on top. Bake for about 10 minutes, watching carefully so they don't get too brown.

Remove from the oven, let cool on a wire rack, and dust with powdered sugar.
