Food and Cooking

Mastering the Art of Soviet Cooking: A Memoir of Food and Longing by Anya Von Bremzen
As almost everyone knows, food is more than just sustenance. The smell of certain meals cooking takes us back to our childhood, making us feel comforted or scared. Food writer Anya von Bremzen grew up in the former U.S.S.R., where food had a special significance, representing everything she could and couldn't have. In her latest book, she and her mother Larisa take on the tremendous project of cooking their way through their own history. Each dish — fish pie, Georgian stew, blini — represents a different time of their life, and with each recipe von Bremzen tells an equally captivating story about her memories from that period. — SL

Before Happiness by Shawn Achor
Some people are blonde; some are brunette. Some people are happy; others are doomed to a lifetime of misery. Right? Wrong, at least according to Shawn Achor, a psychology researcher who's written and spoken on cultivating happiness in the workplace. In his latest book, Achor talks about changing the way we perceive reality so that happiness actually becomes a legitimate possibility. It's all about the small stuff — think keeping a daily gratitude journal or starting the workday by listing everyone's successes. "Before Happiness" is not only an uplifting read — it's also an impressively well-researched book that's still a breeze to read. — SL
