Heat a heavy-bottomed pan on medium heat and sauté all the spices, except the cinnamon, until fragrant, about 3 minutes—don’t step away, as they can easily burn.
Cool slightly and process in a spice or coffee bean grinder (you may need to do this in two batches).
Transfer to a bowl, whisk in the cinnamon, and then funnel into an airtight glass storage jar.
