Preheat the oven to 410°F.

In a mixing bowl, beat the egg yolks with 1/4 cup of sugar for about 4-5 minutes. You'll get a pale yellow foam and the texture of the egg yolk will be slightly denser. Add the vanilla and almond extracts.

In a bowl, combine the flour, finely ground fleur de sel and baking powder. Sift all the dry ingredients.

Cream the butter (2 sticks + 1 Tablespoon) with superfine sugar (whisk using a standmixer to get as much air as possible in the butter). Add the egg mixture and the dry ingredients. Mix well.

Place a silicon mat or a sheet of parchment paper on a baking tray. Spread the sandy cookie dough onto the silicon mat. Place another silicon mat on top of the dough like a sandwich. Even out the dough using a rolling pin to about a 1" thickness. Plastic wrap the tray and place it in the refrigerator for at least 30 minutes.

Remove the first layer of the silicon mat. Get several cookie cutters and cut the cookie dough. Much to my chagrin, I found that using irregular shaped cookie cutters were more difficult to unmold. So either bake cookie-cutter-less or bake with a simple shape cookie cutter like circles or squares.

Bake the cookies for 10 minutes at 410°F.

Remove from the oven and let them cool down completely to room temperature before taking them off the cookie cutters. They will harden and get firm as they cool down.

Bon appétit!

Stay tuned and check back tomorrow and see what I pair this sablé cookie with.
