Growing up my mom always made pignoli cookies during the holidays. They are so delicious and are perfect during the afternoon with a cup of tea or fancy enough to be served for dessert.
I must warn you, however, both the pine nuts and almond paste are a bit pricey. WalMart sells the same almond paste as high-end grocery stores but a few dollars less expensive.
These cookies can be stored, at room temperature, in a tightly sealed container for several days.
