Blood oranges have a, deep, red, flesh and have a stronger aroma then the traditional orange. Pitchfork Preserves uses Moro blood oranges for our special Marmalade. Moro blood oranges are believed to originate from Italy in the 19th century, where a bud mutation occurred producing the beautiful blood orange. Now a delicacy blood oranges are making their way into kitchens everywhere. We welcomed them into ours making Pitchfork Preserves Blood Orange Marmalade, and are already enjoying the experience of their potent and robust flavor. Perfect for slathering on your favorite toast, or on a roasted pork loin, this marmalade is sure to please your palate.
