At 5:30 PM I made thin slices through the thickness of the potatoes and set them into a baking dish. After drizzling them with oil and seasoning them they went into the oven uncovered as I increased the temperature to 350 degrees and removed the rib tips. In order to finish the ribs I slathered them with BBQ sauce and covered them with foil, The top of the stove vents the gas oven so I like to set things in that area to keep them warm, so that is where the meat rested.
We generally eat late, around 7:30 or 8:00 PM. When the potatoes tested fork tender ( about an hour and a half later, the potatoes were large) I covered them with foil and placed them next to the meat atop the stove. 30 minutes before mealtime I placed all three dishes back into the oven to finish. The broccoli was tender crisp as were the potatoes and the pork was melt in your mouth tender.
It was a good day.
