This isn't the sweetest cookie so don't be afraid to use a sweet jam. The previous commenter is right, though; the dough is very difficult to work with because it's so dry and crumbly. I didn't coat the cookies in chocolate - an extra step for already time-consuming cookie - but it didn't matter, because the flavor was fantastic without it. I used homemade blueberry jam. The cookies tasted really good and looked nice, but nowhere near as perfect as the picture. Overall, a tasty cookie good for special occasions that I won't ever make again.
