Mike Whitmarsh is responding to a report that eating fish and chips makes you a bad lover by taking to Plymouth’s Barbican quarter and challenging a few fishermen and passers-by to try caviar instead. The egg-popping public are more amused at the question than the spoonful of black shiny spheres over-lumped onto a cracker! The term caviar is also used for substitute products such as lumpfish, roe from salmon and trout and vegetarian or vegan varieties such as from aubergine.
