You're gonna fall in love after doing your first one oonighttrain.
One thing I have started doing on mine is to toast the corainder first, sometimes I toast the black pepper too but LOVE using toasted coriander on it, gives it more depth of flavor, and when toasting coriander it puts off a really nice citrusy smell.
To toast you simply place the seeds in a pan over low-med heat, stirring constantly until they take on a nice brown color.
As with most spices use caution so as not to burn them, but coriander is a bit harder to burn than most other spices.
Afterward just let them cool completely and crush up.
I like to use the coriander, black pepper, and garlic and occasionally a few things here and there.
Here is a link to some of the toasted coriander and pepper rub I did.http://www.smokingmeatforums.com/for...astrami&page=2
Good luck, and don't forget the Qview.
