Apricot Jam Cookies

One of the many recipes from Carole Walker's book. I noted that drizzle confectioner sugar while rolling is not a good idea as it starts melting so I dusted my table top with plain flour instead. I found out that while baking some of my cookies split open 'cause I didn't bring both ends together and pleat but I just folded one on top of the other. I tried gluing it with egg but this does not work either. It tasted more or less like cream cracker different from the plain sugar cookie.
