I love making turnovers, too bad I can’t have any right now, too many calories. My favorite is goat cream cheese and a touch of homemade blueberry or blackberry preserves inside. Heavy on the cheese, light on the fruit. but sadly no more goat cheese unless I buy it, and the store bought never tasted as good as mine. Since we never kept a buck, fed natural feed and cooled milk down quickly our milk and cheese never had a goaty flavor. Waxing nostalgic.....
I've never used blackberry preserves for turnovers. Maybe it was growing up here with blackberries in season.
I use a lot of apricot preserves for pastries and I'm using orange marmalade a lot for meats and for marinades.
