If you remember, it's not a real recipe.
IN a small bowl I mix about
2 Tbsp's olive oil
1 Tbs garlic
1 tsp worchestershire sauce
1 Tbsp horseradish
1 tsp kosher salt
1/2 tsp black pepper
1 tsp dijon mustard.
Rub all over the roast(Roast should go in the oven at room temp, for even cooking)
. Bake at 400 for about 20 minutes until it gets a little crispy and then turn oven down to 225..You will want an oven thermometer to cook it to desired temp,but slow cooking really makes a difference in taste.
