Slice the top off of each chilli and remove the pith and seeds
Peel your ginger and slice into thin pieces
Peel your onion and slice into quarters
Place the peppers, onion, ginger and garlic on a baking sheet and drizzle on 1 Tbsp of olive oil as well as 1 Tsp of salt
Bake in a 180c or 350f oven for 20-30 minutes until the chillies are cooked and slightly browned. Remove and let cool before moving forward
Place all the baked ingredients into a food processor and process into a fine paste
Add the remaining ingredients apart from the lemon juice and cayenne pepper, then blend until well mixed and a thick chilli sauce has formed
Taste the sauce and see if it's spicy enough, if not, add the cayenne pepper and blend once more
Add the lemon juice and mix in
Place the chilli sauce in a container and refrigerate overnight, the flavors will develop over the next 24 hours
