Every cook's favorite food science reference is Harold McGee's "On Food and Cooking." I use mine often enough to consider it a talisman and whose loss would cause me irreparable psychological damage. I'm sure everyone who has this book feels exactly the same way.
Well, "On Food and Cooking" has been up on Google books for quite some time, and like all books that the Google team has scanned is searchable. Apparently Mr. McGee has buttonholed some Google engineers (I'm guessing he promised to explain Molecular Gastronomy to them as payment.) to build a feature into his site that will allow anyone to search his book from there.
So the next time you need to get scienced up you can go here
Search "On Food & Cooking"
Oddly, my two copies of On Food and Cooking are less than four feet from my desk. But such is the nature of the cyber life that I probably won't be having to get up from my seat to read them much anymore.
