Moody Moons is a witchy blog with tons of good stuff, but I really love this particular take on beginning kitchen witchery. It's straightforward, simple, and to the point. My favorite sort of practical magic!
The Magick Kitchen
The Magick Kitchen is a brilliant site. It's one of the few out there dedicated mainly to kitchen witchery. There is a wealth of information and recipes, along with a special section just for beginners.
This site hasn't been updated for several years from the looks of it, but it's a great blog with so much good information that I hate to see it overlooked. Definitely worth going through for recipes and wisdom.
