We discovered this recipe a few years ago and it is now the only way we cook a Pork Roast

Preheat oven to 500 degrees.  Yes 500 degrees

When it reaches temperature place your seasoned (we use various seasonings depending on our mood) foil wrapped and bake EXACTLY 5 1/2 minutes PER POUND.  

When timer goes off turn oven OFF and whatever you do, do NOT open the oven door. Keep in oven for exactly 60 minutes

Remove and let roast sit for 5-10 minutes before carving.  It will be perfect!! The before and after
