Made exclusively with locally grown blackberries from The Farmstead Market & Hirsch Fruit Farm. I stock up in the summer and freeze as many as I can to make this one last through December. I remember picking wild blackberries in the backyard of my grandparents' house in Michigan, which they would immediately turn into a pie. For that reason, this will always be one of my favorites. Keep at room temp up to two days, then refrigerate. Best eaten with 2 days. Pies are 10 inches and serve 8 generous slices.
