I've used rusks quite a bit, which have the same description as the macaroons. Definitely seemed to help with skill ups in crafting. This is something that is pretty hard to test as sometimes skill ups are very infrequent anyway and then sometimes they come pretty quickly.
I leveled 50-93 cooking while using them and to 99 smithing (along with all the other stuff that isn't too difficult to gain skill ups pre-60 anyway)while not. There seemed to be an increase in skill ups for that time in cooking.
Certainly cannot say for 100% that there is in either food type, but I have seen several places that the macaroon gives increased skill up rate, decreases break rate and affects high-quality yield somehow (both positively and negatively, but have seen more negative). Seen in several different JP bazaar comments and on one of the forums, cannot remember which exactly.
