Wash the scotch bonnet, spring onions, thyme, coriander and parsley.
Trim off the roots of the spring onions and cut into smaller pieces.
Cut the stems off the parsley and the coriander.
Remove the thyme leaves from the stalk. An easy way to do this is to hold the end of the stem with one hand and run two fingers down the stem to separate from the leaves and thinner stalks from thick stalks.
Peel the garlic and the ginger.
Peel the onions and cut into smaller pieces.
Remove the stalk from the scotch bonnet.
Add all the ingredients into a blender with the salt. Add three tablespoons of water to help the blending process.
Whizz all the ingredients in the blender to get a coarse consistency.
