Boston Public Radio welcomed chocolatiers Eric Parkes and Alexandra Whisnant for a special chocolate-themed news quiz. Parkes is the founder of Somerville Chocolate, which is modeled after the CSA (community-supported agriculture) concept in which share owners periodically receive chocolate throughout the chocolate season. Whisnant is the founder of Gâté Comme Des Filles, a Parisien-inspired chocolate business. Parkes and Whisnant answered questions about the week’s news and gave Jim and Margery a tour through the tastiest chocolates on this side of the Charles River.
