When Joe Sopher, 61, retired, he began making the flavoured popcorns he had seen on business trips to the US. After it was spotted by a Selfridges buyer at a food fair, Sopher, together with wife Jackie, 56, and son Adam, 34, moved the business out of the family kitchen and expanded the range. The London firm now boasts 40 flavours and exports all over the world via retailers, airlines, such as Emirates, and its own website. Growth in Asia and the Middle East helped boost overseas sales to £1.7m in 2018.
