Cooking cable is a rather slow method of learning cooking, best would be either preparing a bunch of stuff (which costs money and not always financially possible), book in the library, or working on the culinary career with the learn cooking mode.
Handiness.. i'd go for a book if i'm short on wish slots, upgrading crap seems to just launch you a whole bunch of wishes, which end up expiring or taking over a slot for a long time since upgrading takes a long while.
Nectar making, hmm, a book *may* be worth it to bump a level if there's a substantial reward on that level, say, you're at 6 or 8 and a wee bit and want extended nectariation / improved pressing before making your next batch.
Photography? -> book. Slower, but it won't waste a bunch of money and first time pictures on it.
Logic is another one i'd just go for the book (it's faster past logic 5 than telescope).
