1. A knife: This knife should not be used for anything but cutting the plants you plan on using in your workings. Find one with a wood handle and steel blade that fits comfortably in your hand. Bless it according to your tradition and take very good care of it, as it will be very necessary to your chosen path. (I’ll post a knife blessing later).
2. Mortar and pestle: No special invocation is required for a mortar and pestle but you can feel free to perform one if you wish. Ceramic and glass sets are favored by many kitchen witches for their nonmetallic content, but can break if you aren’t careful. Wooden sets tend to absorb odors and oils and can taint new blends so I wouldn’t advise using them for anything. Metal sets work very well if you plan on mostly blending incense, but for general workings I always use a stone set. Remember to wash and dry it between each use.
3. A large (two quart or so) nonmetallic and heat resistant pot: It should also have a lid, so that you can brew your own magickal liquids (i.e protection oil), or even for boiling large quantities of herbs and tea leaves for health reasons (basil leaves brewed with green tea make an excellent home remedy for menstrual cramps. Gross, but effective).
4. Airtight jars in which to store your dried herbs, blended oils, or incense.
5. A source of flame: Many spells and magickal workings call for the use of an open flame, a gas stove, a fireplace, even a Sterno will do. For kitchen witches, I advise keeping an aloe plant handy wherever you perform the most workings as it is a useful burn salve, and helps ward off fire and burns.
