Geeky foodies, rejoice! Cooking for Geeks: Real Science, Great Hacks, and Good Food ($23) is your savior from a life of greasy takeout and frozen Hungry Man dinners. Author Jeff Potter shows you the science behind food maxims, like the Maillard reaction and why medium rare steak tastes so damned good, while presenting you with easy-to-follow basic recipes and some fun "food hacks". Our favorite part? The interviews and insights from people like Mythbusters' Adam Savage and the xkcd cartoon strip. It'd make a great gift for that geek who finally took the plunge and moved out of his parents' house, and isn't sure what that big, hulking, hot metal thing in the kitchen actually does.
