dissolved and the mixture is smooth and glossy.

Pour the sauce mixture evenly over the raw ribs in the slow cooker, lifting the pieces slightly with a spoon or tongs so sauce can run underneath and around them. Spoon some sauce over the tops so every bit is coated.
Cover the slow cooker with the lid. Cook on LOW for 7 to 8 hours, or on HIGH for 3 1/2 to 4 hours, until the ribs are very tender but still hold together when lifted with tongs. The meat should pull away from the bone easily.

Once the ribs are done, carefully lift them out with tongs and a wide spatula, as they will be very tender. Place them on a platter. If you’d like a thicker, stickier sauce, skim off any excess fat from the liquid in the slow cooker, then ladle some into a small saucepan and simmer it on the stovetop for 5 to 10 minutes until slightly reduced.
Brush or spoon some of the warm sauce over the ribs just before serving, and pass the rest at the table. Serve hot, straight from the platter, with plenty of napkins.

Variations & Tips
You can easily give these ribs your own family touch. For a little heat, add 1 to 2 teaspoons of crushed red pepper flakes or a dash of hot sauce to the sauce mixture before pouring it over the ribs. If you like more tang than sweetness, cut the brown sugar back to 2 tablespoons and stir 2 tablespoons of apple cider vinegar into the sauce. A teaspoon of smoked paprika or chili powder will add a gentle smokiness if your barbecue sauce is on the mild side.
For a slightly less saucy version, use 1 cup barbecue sauce and 1/4 cup ketchup and skip reducing the sauce at the end. If you want a caramelized finish, place the cooked ribs on a foil-lined baking sheet, brush with extra sauce, and broil for 3 to 5 minutes, watching closely, just until the edges start to char.

Food safety tips: Always start with fully raw, thawed pork ribs—never cook from frozen in the slow cooker, as they may stay too long in the temperature “danger zone.” Keep the ribs refrigerated until you’re ready to place them directly into the slow cooker. Make sure your slow cooker is set to LOW or HIGH as directed; do not use a “keep warm” setting for cooking. The ribs should reach an internal temperature of at least 145°F, though for tenderness they will usually be well above that by the time they’re done.
Refrigerate leftovers within 2 hours of cooking, in shallow containers, and use within 3 to 4 days, reheating until steaming hot before serving.
