Put all the ingredients for the paste into a mortar and pound using a pestle for about 10 minutes until the paste is smooth. All the ingredients can also be put into a blender and liquidised. If the paste is too dry, then you may need to add some water.
Once the paste is smooth put the paste into a pan along with the chicken stock and bring to the boil. Add the pumpkin and baby corn and simmer for 2 minutes.
Then add the mushrooms and courgettes and cook for a further 2 minutes. Add the lemon basil and fish sauce followed by the prawns and simmer for another 2 minutes until the prawns are cooked. Turn off the heat and serve.
