Picture your correspondent, a large (corpulent is my sister’s word for it) man, standing in a kitchen in the tropics with barely a foot between his head and the ceiling. The temperature in Galle, Sri Lanka, is a comfortable 29°C (84°F), but it is steamy. Not especially uncomfortably steamy, but steamy nevertheless. I rather like spending my time when not cooking cooling off in the soft, warm rain on my way to the swimming pool and being waited on hand and foot with pots of tea or glasses of gin and tonic.
