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 Regina are an example of Italian cookies that are not sliced and rebaked.
Keep the cookies between sheets of wax paper in a tin or plastic container with a tight-fitting lid at room temperature.
