Mix in a bowl. Rub up the roast really really good making sure you press in the brown sugar crumbles. Refrigerate anywhere from 4 to 48 hours. You can roast it in the oven fat side up at 325 or on the grill. I have a Weber and use the warming rack as indirect heat. Also, fat side up.
For a medium rare doneness, pull beef out of oven or off grill when internal temperature reaches 135. Cover in foil and let it rest for at least 5-10 minutes before slicing.
