For World Milk Day, Chef Neil Forbes and Sumayya Usmani celebrate the sheer joy of milk. Neil cooks up a classic bechamel sauce to go with his pan-fried cod and Sumayya shows us the versatility of almond milk when she makes macaroni cheese. Also, Mary Hillard from Mary's Milk Bar in Edinburgh reminds us about the popularity of milk bars between the 1940's and 60's and how she really enjoys challenging her customers taste buds with some unusual Gelato ice-cream flavours such as beetroot and pickle, goats cheese and even white chocolate chilli and lime!
