On a steamy evening recently, after a wonderful afternoon's cricket, a friend appeared with a glass of Vouvray mixed with orange and grapefruit juices, a slice of cucumber, a sprig of mint, a maraschino cherry and a bright yellow straw. 'What is that?' I asked. 'It looks ridiculous.' 'Everything I could find on the drinks table,' came the reply. 'Why not taste it?' I did. It was delicious.
