Tropical Pineapple Glazed Baby Back Ribs

Why This Tropical Pineapple Glazed Baby Back Ribs Works

In the oven, the ribs sit low and slow for a long time, wrapped in foil. The foil traps steam from the meat and the pineapple glaze, so the ribs stay moist instead of drying out. Over those 2.5 hours, the tough parts in the ribs slowly break down and soften, so the meat loosens from the bone and becomes tender.

While the ribs bake, the pineapple juice, soy sauce, honey, and brown sugar simmer on the stove and start to thicken. The cornstarch slurry turns the glaze from a thin liquid into something that clings to the meat. As it thickens, the glaze sticks to the ribs instead of running off, so it forms a shiny coat.

After the foil comes off and the heat goes up, the outside of the ribs dries a bit and the glaze tightens. The sugars in the honey and brown sugar darken in spots, so the surface gets a sticky, slightly chewy crust while the inside stays soft and juicy.

Mistakes To Avoid

Leaving the membrane on the back of the ribs keeps the heat and glaze from getting into the meat. The membrane tightens and turns chewy in the oven, so the ribs stay tough and the glaze mostly sits on the surface instead of soaking in.

Wrapping the ribs loosely in foil or leaving gaps lets steam escape during the long bake. Without that trapped moisture, the meat dries out instead of slowly softening, so the ribs come out firm and stringy instead of tender and pull-apart.

Pulling the ribs out of the oven too early at the 2.5-hour mark means the connective tissue has not fully broken down. The meat may look cooked and have color from the glaze, but it clings hard to the bone and feels rubbery when bitten.

Letting the glaze stay thin by not simmering it long enough or by adding too much water to the cornstarch slurry causes another problem. The sauce then runs off the ribs in the oven, burns in the pan, and leaves the meat with a sticky film instead of a thick, glossy coating.
