Preheat oven to 250F.

Prepare the ribs by trimming off fat and seasoning with salt and pepper.

Wrap the ribs in foil and bake at 250F for 3 hours.

Meanwhile, prepare the BBQ sauce by combining the whiskey, brown sugar and the chili sauces together. Set aside.

Remove the ribs from the oven.

Preheat the oven to 400F.

Remove the ribs from foil, place on a cutting board and carefully cut into individual ribs with a sharp knife. The ribs will be very tender at this stage.

Place the ribs in a large deep baking dish. Pour the sauce over the ribs, making sure that all ribs are covered.

Bake the ribs uncovered for about 1 hour, turning them and basting in sauce every 10-15 minutes, until the sauce has thickened to your liking.

Remove from the oven and serve immediately.
