I took the advice years ago from one of the employees of the Spice House when making any spice blend, and that is to mix, and mix until you think you can no longer mix. That’s where my KitchenAid mixer comes into play. If you do not have a mixer, then simply get a whisk out and whisk for about 5 minutes.
So the process is simple. Add everything to a mixing bowl, and mix for 5 minutes. Once done, pour into sealable bottles, and give away as gifts. Again, this roughly made about 5 cups, so I had some reserved for myself as well.
