Online freely available cookbooks As a programmer, I'm used to have a lot of online books for learning about almost everything.

I'm sure that there are some cookbooks hidden in the web... but I've found just a few of them...

I know that there are a lot of great websites teaching cooking skills and collecting recipes (and my RSS reader is always exploding with great tips and recipes), but sometimes I prefer to have a whole book in my (virtual) shelves...

So I thought we could create a list of available online free cookbooks, like the programming books one on stackoverflow.
This is an incredibly useful Hydrocolloid Recipe Collection if you are interested in modernist techniques (so called molecular gastronomy).
