Ok, this is the third time in my life I've decided to incorporate tofu into my diet. I picked up an extra firm block...but my problem is that I never know how to prepare it. Then I get frustrated and toss it all out.

Can anyone recommend a web site or a book that instructs you how to really cook tofu? I'm looking to make side dishes and main meals out of it. How do you drain it well, prepare it for different types of cooking, etc.?
