Place the spices in a small frypan over low heat and toast for a few minutes until fragrant.
Place the chilli paste, toasted spices, garlic and salt in a mortar and pestle and pound to a coarse paste. Add oil to loosen the paste and stir through dried mint leaves if using.
Place in a sterilised jar and store in the fridge until required.
Notes
You may use a small food processor instead of a mortar and pestle.
