Preheat oven to 375 degrees.
Let roast come to room temperature for 30 minutes.
Rub the olive oil all over the roast.
Mix the spices and rub well all over the roast.
Bake for 1 hour and then turn the oven off.
Do not open the oven door for 3 hours… At all…for any reason…
After that time passes, turn oven on again at 375 degrees and let the roast come back up to temperature for 30 minutes.
Remove from oven and let rest before slicing.
