Someone gave me this awesome book called The Urban Homestead for Christmas this year. It is the most comprehensive guide to city self sufficiency I've found. It will definitely change the way I eat this year.
Boyfriend's mom and I are planning on expanding her garden this spring to take over her entire back yard. She was already planning on putting in raised beds, which this book advocates for small scale growing. I'm going to create indoor compost bins for both of us that utilize worms to get the most out of composting in a small space (ew, worms?! yep). I'll post step by step photo instructions on how to make them once I figure out where to get my worms.
I did some food preservation last summer and fall--mostly canning, some freezing. This book's authors are big supporters of fermentation and drying as means of preserving food. These methods are old, time-tested, and introduce our stomachs to lots of healthy bacterical friends (Bacteria and worms?! Disgusting!).
I happened to get a food dehydrator for Christmas as well, but I can't really use it until I have some fresh fruits and vegetables to put in it. I will, however, be making cheese, yogurt, and sourdough bread before winter's over. Look for updates on these projects! (In less than 3 months.)
