Almond Cream for tarts & pies !!!

To make almond flour:
1 cup (125 grams) slivered almonds
1/2 cup plus 2 tablespoons granulated sugar
1/4 cup all-purpose flour
1/2 cup plus 1 tablespoon room temperature unsalted butter
1 large egg It is possible to buy almond flour (use 1 cup if you do) but it just as easy to make your own. Place the slivered almonds (no skin preferred) and granulated sugar into the food processor. Pulse until the almonds and sugar reach the consistency of flour. It is best to pulse because the heat of the blade will cause the release of the oil from the almonds.Mix in the flour. Mix in the butter. Add the egg and mix until the mixture becomes light and creamy. Do not overmix or the gluten in the flour will overdevelop and the almond cream will lose its delicate texture when baked.
