It's Home Dairy with Ashley English, and it is the perfect reference for making yogourt, cheeses, and butters. It's beautifully laid out, the pages have a lovely texture and smell like Grade 4 (Mmmm!) and the instructions are clear, well-written and logically ordered. I LOVE it, and will be buying my own copy with my next Air Miles redemption. (That's how I keep myself from spending all of my money on books!) If I had some extra cash lying around, I would give you all copies. But since I don't, go to your library's website immediately and put a hold on it. Then you'll read it and decide that you need to buy a copy, too. I promise.
Ashley English is also on Twitter, and she has a great blog, Small Measure. There are also three other books in this series, which I am assuming are just as excellent (and I've read positive reviews, too!): Keeping Bees, Keeping Chickens, and Canning and Preserving. If one of you has a bazillion air miles that you want to redeem for Chapters gift cards for me, please feel free. I will happily accept! Really, this book is worth your time. I promise.
**Edited to add: I was so excited, I forgot to include three of my favourite things about the book! Firstly, it was manufactured in Canada, a rare thing to see these days, and secondly, there is a section of body care recipes! Third, there are instructions for a cheese press, which I don't know if I'll ever make, but I love that it's in the book.**
