Shell the cardamom: Gently crack open the green and black cardamom pods with a mortar and pestle (or crush them on a cutting board using a heavy pan). Remove the seeds and discard the husks.
Grind the spices: Finely grind the cardamom seeds, cinnamon sticks and cloves in a spice or coffee grinder. Store in an airtight container away from direct sunlight for up to 1 year.
