Preheat your oven to 300 degrees. Line a baking sheet with a couple layers of foil. Place the ribs on the foil like so, making sure to not overlap.
Wrap the ribs up in the foil like a package. Bake for 2 1/2 hours.
Take the ribs out of the oven. Open up the foil package.
Turn on your oven’s broiler. Move the oven rack 6” away from the broiler. Broil your ribs for 8-10 minutes until they get a slight char.
While the ribs are broiling, mix together the calamansi juice and banana ketchup to make your glaze.
Turn your oven back down to 300 degrees, putting the oven rack back in the center of the oven. Brush on a thick layer of the glaze. Bake for 10 minutes. Glaze the ribs again and bake for another 10 minutes.
Take the ribs out of the oven and brush with one more layer of glaze. Let rest for 10 minutes before serving.
Cut in between the bones. Serve with garlic fried rice.
