Taking the train from Bangkok in 1987, my good friend Nitza and I travelled down to Penang, in Malaysia. The journey took us through a verdant landscape dotted with small villages surrounded by paddy fields. One of the most memorable aspects of the journey was the Thai Blue Swimmer crab curry served in the buffet car - spicy, delicious and a million miles away from the ubiquitous stale British Rail cheese sandwich. Cooked in a huge wok in the tiny galley next to the buffet car, this was a symphony of flavours in every bite, with the sweet, spicy, and savoury elements coming together to create an epic and satisfying culinary experience.
