I got this from the Penzey's spice catalog. My family just loved it. Note: It calls for English Prime Rib Rub, which is a spice blend Penzeys makes. I mixed together equal parts ground celery seed, garlic powder, onion powder and sugar. Then measured out the 1-1/2 teaspoons of this mixture to replace the prime rib rub. It tasted great! If you do have this mix from Penzeys, omit the salt and pepper as the mix already contains it.
