Add all ingredients and marinade in bag overnight removing all air
Pre heat oven to 500 Deg
Remove roast from bag and dry with towel
Put roast on rack in shallow pan salt and pepper
Place in oven reduce heat ot 475 deg cook 21 minutes or 7 minutes per pound
Turn off oven and leave in for 2 and a half hours do not open oven
I use blue tooth probe thermometer to track temp as I like more rare
Here is where things failed at 108 Deg the temp started to go down
I finally opened oven at 104 deg and it was cold
I cranked oven to 350 deg as I was hungry
When probe read 130 Deg I removed wrapped in foil and rested 10 minutes
Roast ended up over cooked and maybe med well at best
I do have confidence this method works just not with my oven
