Pork ribs are a popular addition to the south american grill. They are prepared many different ways in south america, unlike beef ribs (which are normally seasoned with salt only and grilled in the traditional argentinian style-directly on a hot grill or on a spit over an open fire). Pork ribs benefit from longer, slower cooking, with marinades and glazes. Citrus and chile peppers are commonly used for seasoning pork. You can cook these ribs entirely on the grill, using indirect heat, if you have time to hang out near the grill for several hours, maintaining the temperature and checking on the ribs. (add some wood chips for extra flavor). Or you can roast them at a low temperature in the oven ahead of time, then finish them on the grill to get that essential smoky flavor. Marinate the ribs overnight if possible.
