Not as geeky as it sounds...

Cooking for Engineers is a site that does a great job showing you exactly what you're supposed to do to make any of their recipies. They include pictures of the various stages of the process, give visual organizers at the end of each recipie to recap the process, and they test various adjustments to the recipies to make sure things are working about as well as they can.

I've tried a few of their recipies and have had good luck so far.

Along the same vein is America's Test Kitchen who produce Cook's Illustrated which is easily my favorite cooking magazine - no ads, wonderful use of the scientific method, great recipies, neat visual style - but their online presence is behind a paid registration that I don't want to pay for. Their primary cookbook is, however, the best I've ever used. Amazing recipies.

Now, get cooking...
