4 spring onions, finely sliced
2 lemon grass stalks, chopped
2 cloves garlic, chopped
2cm root ginger, peeled and chopped
6 dried red chillies
handful chopped coriander (keep a little for decoration)
tsp each ground coriander and ground cumin
juice of a lemon
Put all ingredients in a blender and blitz until a smooth paste forms. No need for any oil as the juice will come out of the onions and ginger.
I used dried chillies but if you have fresh use them, or if you can't find either, put in a couple of guindillas but wash thoroughly to remove vinegar.
If you don't have lemon grass throw in some chopped lemon rind.
