He's written some of the most evocative books about chefs around (Reach, Making, and Soul Of A Chef), devoted an entire glorious cookbook to Charcuterie, and allows Anthony Bourdain to post on his blog. Yeah, he's pretty cool.
As a companion to his new book — Elements Of Cooking — Ruhlman has added another blog to his portfolio. Like the book, it explores "what is fundamental to the act of cooking," including in-depth discussion of the uses of ingredients, techniques and foundational recipes. Anyone who is interested more in the background of cooking (the why of technique) than in following recipes should check it out.
