4slicesof cheddar cheese(optional for cheeseburgers)
Place the blueberries in the the bowl of a food processor and pulse until powdered. In a large bowl, combine the blueberries with the beef, salt and several turns of the pepper mill. Mix and knead the beef until all ingredients are evenly incorporated.
Form into 4 burgers. Pan-fry or grill according to your taste. If making cheeseburgers, add cheese about two minutes before the end of cooking time.
Place the burgers on buns and serve with ketchup or chilli sauce.
Frost is a common problem with wild blueberries and is the primary cause of a poor harvest. Not all blueberry farms have the same climate. The fields in Quebec and Maine blossom before the fields on Prince Edward Island and are therefore more susceptible to frost. The later blossoming of Island berries usually occurs after the last frost of the spring.
