Authentic Close To Katz's Pastrami Rub

Method1) If you wish, you can use only powdered coriander, ground black pepper, and ground mustard, but I like using some whole seeds. If you are using some whole seeds, pour them into a zipper bag and smash them with the bottom of a sauce pan so they are "cracked" but not completely powdered.2) Blend together all the spices. Rinse the meat, and while it is damp, apply the rub liberally, about 4 tablespoons per square foot of surface, and press it into the surface to help it adhere. If there is a thin part of meat, use less rub.
