Planning to watch Food, Inc., on April 21 on PBS? Great opportunity for a potluck, POV points out. It’s encouraging viewers nationwide to meet, eat and watch the Oscar-nominated doc. Potluck hosts can register for prizes including books, gift cards and sustainable food items (dub those winners “potlucky”). Don’t know what dish to bring? Fear not, there are recipes too. The POV staff is throwing its own potluck next week in the office, sort of a test run for the big event. Simon Kilmurry, POV’s executive director, tells Current he’s bringing cloth napkins to ensure it’s a classy affair. No word on whether he’ll also bring the Parsnip Pancakes.
