Liberally season an pork roast with a rub. Brown well on all sides. Cook in an oven pre-heated to 375F to an internal temperature of 160F. I use a temperature probe because I can. Let rest for 10 minutes. Deglaze the pan on cook top with chicken stock. I usually toss in some dried shallots. The roast cooks quickly, maybe 30 minutes.
Peel and cut potatoes to a medium dice. Add a couple of table spoons of oil to a saute pan and cook until golden brown, about 30 minutes. Sometimes I add onions.
