This is an old fashioned cooking term which means to prepare meat, poultry or fish with sharp, hot seasonings before grilling or roasting. According to Dr Kitchener, who was a British optician, telescope maker and cook, devil sauces seem to be aimed at men in the 1800s. He wrote a book called the 'Cook's Oracle', which was popular in the UK and the US, where he wrote: 'Every man must have experienced that when he has got deep into his third bottle.... his stomach is seized with a certain craving which seems to demand a stimulant.' Devilling was also a popular way of serving up leftover roast meat, by smothering it in hot sauce and reheating it. Alongside his love of devilled sauces, he also used to invent new sauces, such as 'wow wow' sauce, which is a mustard and ketchup based spicy sauce with pickled walnuts.
