Ok, a major sneezing fit later, I got the chipotle peppers all ground up and into a container. Since I'm working at a different plant this week, I'll be doing the chipotle rub late in the week or early next.
After the peppers are dried to the point that they are crunchy, put them into the blender and let it spin. Pulse it now and then to make certain all of the parts are ground finely.
Next, I strain the powder through a seive to get out any seeds or pieces that didn't grind up. This is the part where I recommend that you DON'T inhale deeply.
Now you can use the chipotle chili powder for most anything!
Like I said above, 2 pounds of the raw peppers provided 4 ounces of dried peppers and 3.5 ounces of powder.
If you do this, keep some Kleenex handy, you WILL sneeze!
