A smoker, a grill set up for indirect heat, or a low oven for around three hours. Rub them the night before if you think of it. They're ready when the meat has pulled back from the bone and a toothpick slides in with no resistance.

Brown sugar, paprika, salt, pepper, garlic powder and a little cayenne, rubbed on and left overnight. Then 250 degrees for around three hours, wrapped for part of it. They're ready when a toothpick slides between the bones with no resistance. Sauce brushed on at the very end and set under heat ten minutes. Slaw, cornbread, and cold drinks.
Arrives frozen and vacuum sealed, and keeps about a year in the freezer. Thaw it overnight in the fridge, or quick thaw it in a bowl of cold water. Once it's thawed, keep it in the fridge and cook it within 2 to 3 days.
