You'll see two main types of ribs at the store: baby backs and spare ribs. Baby backs come from near the spine, are smaller and leaner, and cook about an hour faster (they're also easier for a beginner). Spare ribs come from the belly side, have more fat and connective tissue, and reward you with deeper pork flavor which makes most competition pitmasters prefer them. If the packaging just says "pork ribs" with no label, flip them over: baby backs have a distinct curve and shorter bones, spare ribs are flatter with longer, straighter bones. A good buying rule of thumb: one rack of baby backs feeds 2 people, one rack of spare ribs feeds 2-3. And if you're at Costco, their racks usually come with the membrane already removed which saves you some time. Whichever you buy, when you open flip the rack over and peel off the thin membrane (silverskin) on the bone side. Grab a corner with a paper towel and pull it off, it should remove itself in one sheet. Leaving silverskin on blocks smoke and seasoning from penetrating, and it turns rubbery and chewy no matter how long you cook.
Ribs are the one cut where you must fight every instinct to rush. Low temperature, long time, no shortcuts — that's the entire formula. Most people who end up with tough ribs pulled them too early; the meat is technically safe at 145°F, but it won't be tender until it hits 195–203°F, which is where the collagen has fully melted into gelatin. Below you'll find times for oven roasting, smoking, grilling indirect, Instant Pot, and slow cooker.
Ribs need 195–203°F for pull-apart tender meat which is way above the USDA minimum of 145°F for pork. At 145°F the meat is technically safe but will be tough and chewy because the collagen hasn't had the chance to break down. A long, slow cook at 225–300°F for hours makes food safety a non-issue. You can use a thermometer to check temp, but it can be a challenge for ribs since the meat can be thin and bones throw off readings. The key is inserting into the thickest meat between two bones at an angle to avoid the bones. A test that a lot of the pros use is the "bend test." To do this, pick up the rack from one end and if it bends deeply and the meat cracks on the surface, it's done.
