My worst food memory is from the early 1950s. As a four year old child I spent 9 weeks in hospital (in my UK home town). They used to serve white fish with mashed potato. To this day the taste and texture of white fish makes me heave.

My best food memory dates from a business trip to Thailand in 1992.
I was working in a factory, on the edge of a small market town, about 20 or 30 miles from Bangkok. Every lunchtime I and my colleagues were taken to a restaurant in the town. It always seemed as if half of the people working in the factory came with us on these occasions (Thais are very sociable people). The tables in the restaurant would be loaded with piles of delicious food - all flavoured with exotic and (at that time) unfamiliar herbs and spices like sweet basil, lemon grass, galangal and, of course, loads of chili! It still makes my mouth water just to think of it. How I managed to work in the afternoons I shall never know!
