Biscotti is the plural form of biscotto. Bis- means twice, while -cotto means cooked or baked. These crispy cookies are baked twice to give them a super crispy texture and a dry state which allows them to be kept for weeks. This is one of the easiest cookies to make. The dough is made with creamed butter and sugar, eggs, flavoring and fillings (like nuts, raisins, etc), and then the dry ingredients (flour, salt, and baking powder). It's quite a sticky dough. So the only tricky part is forming them into two long and flat logs for the first baking -- well-floured hands are necessary to avoid sticking. After they are baked to fairly firm and starting to crack on top, they are cooled slightly and sliced. The sliced cookies are baked again on both sides to dry them out quickly. I followed the recipe from The Best Recipe that included almond extract, orange zest and toasted almonds. Yum!
