I was given a copy of Cook's Illustrated:
http://www.cooksillustrated.com/This magazine is amazing, if you like the "scientific" method of cooking. For a single recipe, for instance, they'll tell you all the different things they tried and what didn't work out. If you're a "get to the punchline" type of person, however, you won't like this technique. For me, it's great -- it's like an entire magazine written by Alton Brown. I've only tried one of the recipes, a Mexican version of chocolate butter cookies where you put cinnamon, slivered almonds, and cayenne pepper, heated then ground, into chocolate butter cookies made with dutch-process cocoa and espresso powder. We also put a chocolate glaze of Valrhona chocolate on top and then put some white chocolate drizzle (both of which were recommended by the magazine) to add some eye pleasing texture. Oustanding! Very complex, with multiple layers of flavors -- Akin to a good Scotch.
They also review products (and they accept no advertising) and have helpful tidbits.
Anyway, if you like to cook and desire a magazine having a more scientific approach to cooking, this is the magazine for you.
