Consider me a sucker for punishment. I'm indexing all my bread recipes: which book, what page, a quick ingredient summary. I am on my 36th book (almost done with the Bread books, then on to Baking, and finally General cooking), and I have over 4000 recipes; not all are bread or even baking - some are icings, sauces for pizza, etc. I got the idea from a comment Floyd dropped idly some time back.
It's been fun seeing what recipes I have. Some of these books have never gotten a decent look-see, but now I'm making interesting-looking recipes out of them.
