Salted Caramel Macarons

almond flour

powdered sugar or confectioners sugar

large egg whites (at room temperature)

granulated white sugar

cream of tartar

heavy cream

- 2 tablespoon granulated sugar [you can use 1 cup (I took out 2 tablespoons because the macaron shells are already quite sweet])
