From Purpose site: "Selfridges wanted a special chocolate, to coincide with National Chocolate Week 2008, and the fact that – due to world events – people are spoiling themselves with little 'treat' purchases. Purpose worked with restaurateur and Food Writer Laura Santini, and The Chocolate Society to produce some Hokey Pokey with a topical twist."
