Peanut butter has fanatical addicts, bizarre recipes, strange non-food uses, & even a secret adult peanut butter fan club! The PB Advisory Board's Leslie Wagner explains the product's origins as a health food, the cereal company that has the buttery first patent, and more than a dozen callers sharing their unusual concoctions like peanut butter in a hamburger, ham salad, pumpkin soup and mashed potatoes. March 1st is the celebration of National Peanut Butter Lover's Day! From WHO radio in 2000.
