Step 1

Put the shallots, scallions, ginger, garlic, cilantro, soy sauce, fish sauce, salt, pepper, and sugar in the bowl of a food processor. Process to a loose, finely chopped paste, scraping down the sides of the bowl once or twice.

Step 2

Place pork ribs in a large bowl or a pair of heavy resealable plastic bags. Thoroughly coat the ribs with the marinade, massaging the paste into the flesh for a minute or so. Cover and marinate at room temperature for 2 hours or up to 5 hours in the refrigerator, tossing the ribs once or twice during this time.

Step 3

Preheat oven to 350°F. Spread the ribs out, bone-side down, on two large, parchment-lined baking sheets and bake until ribs are deeply colored and very tender but not yet falling from the bone, about 11/2 hours, occasionally rotating the pans to encourage even cooking. Remove from the oven and serve with small bowls of Thai Chile-Herb Dipping Sauce .
