Harvested by hand from wild trees, Wild Harvest Fancy Large Black Walnuts feature a rich, bold flavor perfect for adding to your favorite recipes. Non-GMO Project Verified. Due to the thickness of the Black Walnut Shell and the inner shell pieces as we process you cannot get whole or halves. Our Fancy Large piece is the largest size that we can extract from our process. Black Walnuts are most used in heirloom recipes to add the bold rich flavor.
