It's tangy, cold and roughly the color of Pepto-Bismol (but, mercifully, not the flavor).This year, Susan wants to know your stories about making the relish, or hating the relish, or not caring a bit about the relish. She hopes you'll be polite. But funny.Fill out the form below — or here — and your response may be used in an upcoming story, on air or on NPR.org.
