Prepare a roasting pan by firing it off with enough oil to cover the bottom in an oven set to 400F. Boil the prepared potatoes for five minutes. Allow to cool and slit potato four times lengthwise along their rounded slide.
Place potatoes in the hot, dangerous roasting pan flat side down and spoon hot oil over the top. Attack with salt and pepper and return to oven for 20 minutes.
Vary carefully: pry the potatoes (hot oil pan risk) open slightly and lightly cover with bread crumbs before allowing to cook for an additional 15 min or until brown.
