Standard ingredient lists omit the physics of connective tissue breakdown, which requires sustained moist heat to convert tough collagen into gelatin without drying out the meat. Pressure cooking accelerates this hydrolysis by raising the boiling point of water inside a sealed vessel, forcing moisture into the pork fibers within a tight 25-minute window. Without this enclosed steam environment, ribs cooked via dry heat alone would seize up and toughen long before becoming tender. Controlling the internal humidity prevents the lean muscle proteins from tightening excessively under rapid heat.
Achieving structural contrast requires shifting from moist heat to dry radiant heat immediately after pressure release. Transferring the softened slab to a broiler set on high creates rapid Maillard reactions on the exterior sugars, turning the barbecue glaze sticky and dark within five to ten minutes. Leaving the meat under the broiler too long carbonizes the tomato solids in commercial sauces, introducing an unpleasant bitterness that overpowers the pork flavor. Monitoring the surface closely ensures the sugars caramelize precisely without burning.
Using bottled barbecue sauce versus a homemade blend changes the viscosity and sugar burning point significantly based on corn syrup content versus natural molasses. Commercial formulas often contain high-fructose corn syrup, which scorches much faster under a 500-degree broiler element than homemade sauces heavy on vinegar and spices. Adjusting the final glaze thickness prevents premature charring while building a lacquered exterior coat. Applying sauce in two stages—a preliminary drizzle inside the pot followed by a thick surface brush before broiling—maximizes flavor adherence.
Leftover cooked ribs store safely in an airtight container in the refrigerator for up to four days, though the texture degrades if reheated improperly. Reconstituting the meat requires wrapping the slab tightly in foil with a tablespoon of water to recreate steam, then warming it in a 300-degree oven until heated through. Microwaving leftover pork ribs liquefies the rendered fat too quickly, leaving the remaining protein rubbery and dry. Proper storage preserves the internal moisture balance achieved during the initial pressure stage.
