Merry Meet all. I like Cunningham's Wicca in the Kitchen, but I enjoy and use Telesco's A Kitchen Witch's Cookbook more often.
Cunningham's book is a good place to go for choosing ingredient's that have a significant magickal meaning and is written in Encyclopedia format. I agree with Mummy_Tummy that Telesco's has more folklore and interesting tidbits in it.
I haven't come across the other books mentioned, but I will have to check them out.
