Toast whole spices (if using) in a dry skillet over medium heat until fragrant. Allow to cool slightly then grind to a fine powder using a spice or coffee grinder. Ours is Krups and we LOVE it!
Whisk all ground spices together (you may want to sift using a small, fine mesh strainer to ensure any big pieces from freshly ground spices are removed). Store in an airtight jar or spice container in a cool, dry place.
