My apologies for accusing you of boiling.
I simply put mine on the barbeque pit raw (offset heat source). I add Jack Daniels pellets to the fire in a smoker box. I let them smoke for 20-30 minutes, then flip them every 30 minutes for two hours. I finish them with some Jack Daniels original BBQ sauce on the grill. The vinegar cooks off leaving a sweet, thick glaze over juicy, flavorful ribs.
