It says something when you plan your family holidays to coincide with locations of great chocolate shops. So it was that we found ourselves in the Peak District, all magnificent green and drizzle while the rest of the country baked. When I told my children we were going to Misco’s in Leek – purveyors of the legendary cake balls (from £5.50 for two) – there were no complaints. The (flourless) cake balls were still being dipped when we arrived, so we wandered round Leek while we waited and got chatting to a woman in a shop who had never had a Misco’s cake ball even though she was right across the street.
