Start pressing the salt mixture all over the roast, tops and sides to 1/4 inch thickness.
Place in your preheated oven (450) for 10 minutes.
After that reduce the temp to 250 degrees and cook an additional 1 hour and 40 min.
Note: 20 minutes per pound.
With a meat thermometer, the temp should reach 120 degrees in the center part of the roast, if you like it pink. If you like it medium cook internal temp to 130 degrees.
