Char all the vegetables. Keep the garlic skin on to avoid burning it. Use a frying pan to char them. No need to add oil or anything. Just put the tomatoes, onion and garlic on the hot frying pan and char them until blacken. Peel the garlic before putting it into the blender.
Soak the morita chillies in hot water. When they are soft, they are ready to make the salsa. I left mine for 10 min in the hot water.
Add all the ingredients in a blender and blend until smooth.
