together 6-8 yellow chilies, 1 chopped lemon grass stalk, 4 peeled
shallots, 4 garlic cloves, 1 tbsp peeled chopped fresh root ginger, 1
tsp coriander seeds, 1 tsp mustard powder, 1 tsp salt, 1/2 tsp ground
cinnamon, 1 tbsp light brown sugar and 2 tbsp oil in a blender or food
processor. When a paste has formed, transfer to a glass jar and keep in
the fridge.
