Preheat the oven to 425 degrees F and make sure the oven rack is in the center position.
Line a baking sheet with aluminum foil. Place the potatoes on the baking sheet. Rub with the oil, and season with the salt and pepper on all sides.
Bake until fork-tender, about 1 hour.
To make the Special Sauce, in a small bowl combine all the ingredients and stir well to blend.
Remove potatoes from the oven and let sit for 5 minutes. Using oven mitts or potholders, carefully transfer the hot potatoes to a plate and serve with the Special Sauce. Serve optional toppings, as desired.
