Preheat oven to 350 degrees.
Cut ribs into sections of 2 ribs per section. Season lightly with salt, pepper and a little garlic powder.
Line a baking pan with heavy duty Reynolds wrap, using ample wrap to cover all four sides and completely enclose and seal the rib sections.
Place the ribs in the foil-lined pan, adding 3-4 ice cubes and seal the foil. Repeat if you have more ribs than will fit into one pan.
Place in the oven and cook 30 minutes. Meanwhile, heat grill on medium-high heat.
Move the foil package of ribs from the oven to the grill, leaving the foil sealed, and cook for an additional one hour.
Remove ribs from the foil and place on the grill for an additional
15 minutes, basting with your favorite BBQ sauce.
