First published in 1855, I'd recommend this book to anyone writing historical fiction. It is an exhaustive description of life in early Canada, including recipes and directions for cooking in a fireplace with a cooking pot. (She advises buying a stove if one can afford it because there's less danger of burning your skirts than there is at a hearth!) She also has gardening tips that I think I'll try. Those never go out of date!
Among other things, very practical advice on keeping track of your serving spoons and dishes when going to a potluck, lest you fail to bring them home again.
