Preheat a saucepan over medium heat and add the oil to it. Add the mix of coriander, cumin, cloves, cinnamon, nutmeg, star anise, and chillies, along with the cumin, mustard seeds, and turmeric. Stir for about 1 minute. Once you start getting the fragrance, add the onion, ginger, and garlic. Stir for about 2 minutes until the onion softens.
