As a new bride I stumbled upon a website called Hillbilly Housewife. Miss Maggie, the owner, has developed and tested dozens of frugal recipes. I think her collection of basic country cooking is truly the best of its kind. If you haven't visited in a while, she's added some new recipes and articles to help you combat this winter's high prices. I particularly like the one about which convenience foods can be good buys.
Incidentally, Miss Maggie is the author of the oft-forwarded article, Apron Evangelism. She speaks from the heart!
