Place frozen roast in water with salt in refrigerator for up to 2 days. This brine is optional.
Peel the garlic cloves, keeping them whole.
Take defrosted roast and gouge a steak knife into the side about 1 " deep every 2- 3 inches, then twist to make a hole large enough for a clove of garlic. Push garlic into the holes, flip roast and repeat. Brush sauce over both sides pushing into any openings not completely filled with a garlic clove.
Place roast into roasting pan or glass oven dish.
Broil on low for 5-7 minutes about 5 inches from the heat.
Turn oven to 235 degrees and place covered roast into oven.
Bake till thermometer inserted in center reads 150 degrees.
Remove from oven and slice. Place meat back into pan with all juices and sauce and bake for another 10-15 minutes at 400 degrees or until it is cooked to your preference.
