Carefully, heat a heavy skillet over medium-high heat until fully heated and slightly smoking.
Add all ingredients and shake and stir for about a minute, or until the spices smell toasted, are slightly darker, and give off just a slight bit of smoke. Remove from the heat and let cool.
Grind to a fine powder in a spice grinder or with a mortar and pestle, and store in an air-tight container.
Note: this is not a very spicy mix; use it for flavor not heat. This is also infinitely adjustable; if you don't like certain flavors or want to adjust their intensity, just play with the proportions of the spices.
