First, make the batter. Mix together the rice flour, salt, sugar, coconut milk, water and turmeric until the batter is smooth. Wash and dry the prawns and chop roughly. Wash the bean shoots and set aside. Dice the pork. Heat a small frying pan and pour in a little oil. Add the pork, onion and prawns and cook, stirring constantly until the prawns change colour and the pork is cooked through. Pour over the enough batter to cover the ingredients, top with some bean shoots and cover with a lid. Cook for two minutes until crisp. Turn over and cook the other side until golden. Make the dressing by mixing all the ingredients together and stirring well. To serve, place a vietnamese mint leaf on a piece of the crepe. Enclose in a lettuce leaf and drizzle some dressing over. Eat immediately.
