Tart Michigan Montmorencies are most commonly baked into pie, but true devotees eat them out-of-hand at market stands throughout Northern Michigan. American Spoon Sour Cherry Spoon Fruit celebrates the vibrant tartness of Michigan's most famous fruit in this thick jam sweetened with concentrated fruit juice and filled with whole bright-red cherries. Spread it over toast or swirl it into yogurt for a simple, satisfying morning meal. No sugar added.
