Product Details Return to Top Overview The recipe for Heritage shortbread has remained a family secret for over a century. It traveled from Scotland to South Carolina, where Willow McGrain’s granddaughter and namesake keeps it close. Now the company is innovating by infusing its gourmet shortbread with pure lemon oil. Perfect with tea, these melt-in-your mouth delights finish with the essence of pure lemon. 18 cookies per box.
