We are really digging food52's latest website addition, foodpickle, a real-time food help line. Just send questions to @foodpickle on Twitter, and you get back responses from a community of cooks. Questions and answers also get posted to the foodpickle page on the site, and there is already an interesting wiki of food knowledge shaping up. But there is an unanswered stumper lingering: How does one prepare the fruit of the kousa dogwood tree? Chowhounds, is it edible?
