Preheat your oven to 400°F (200°C).
In a small bowl, combine the salt and sugar.
Prepare the ribs by removing the membrane from the back of the rack.
Cut the rack into double-rib portions, or leave it whole, as desired.
Rub the salt and sugar mixture evenly over both sides of the ribs.
Place the prepared ribs on a baking sheet lined with foil.
Roast for 1 hour and 20 minutes, or until the crust is golden brown and the meat has receded from the bone ends.
Allow the ribs to rest briefly before slicing and serving.
