Biscotti Regina

These are a delicious Sicilian cookie, widely available in industrially made versions. I assume that the regina (queen) in question is Margherita di Savoia, the second and much beloved queen of a united Italy. Queen Margherita loved sweets and would often go personally to visit pastry shops with her ladies in waiting. She was known to spontaneously ennoble the owner of a pastry shop where she really liked the cookies, elevating him to the rank of cavaliere (knight)! Biscotti R
