Well, ideas for the cookbook I'm sort of working on right now. I also have ideas for other cookbooks if I ever finish one!
I think I might include a special section on breakfast/brunch foods for Yule, since some people have sunrise rituals. At Imbolc and Samhain, some people stay up all night. I might include some special recipes for those nights as well. I'm also working on some alky-hol recipes! w00t!
