Amaretti cookies are gluten-free Italian pastries made with almonds, egg whites and sugar. A great classic of Italian cuisine!The special feature of these delicacies is the presence of a small amount of bitter almonds (armelline) in the dough. Armelline are obtained from the kernel of the apricot.They give the particular intense and somewhat bitter (“amaro“) taste. Hence the name “Amaretti” for these Italian cookies.
