Sour cherry preserves from Michigan's Montmorency cherry season, cooked in copper kettles 60 jars at a time. American Spoon has been doing this in Petoskey, Michigan since 1982, working directly with farmers and foragers who grow and gather the fruit. The gap between this and a grocery-store jam is the difference between something that tastes like fruit and something that used to be. Glass jar, 9.5 oz.
