Plan ahead the ribs need to marinate for a minimum 24 hours, also the sauce can be prepared up to 5 days ahead, but must stay in the fridge for a minimum of 24 hours as well as the ribs, so plan this a day in advance. Start this recipe early as the the ribs will take around 3-1/2 hours cooking time in a slow oven, plus they will need to be chilled for 2 hours with the cider vinegar/liquid smoke seasoning before even roasting them. The first time I made these, I baked them in a lower temperature oven for the 3 hours, I have also made these in a 350°F oven for about half of the time, I have to say that the slower roasting time makes for a more tender rib. You can roast them either way you want. Just wait until you taste these ribs!
