2 tablespoons Pi'xian chili bean sauce (郫县豆瓣)
0.5 teaspoons ground Chinese red pepper (花椒粉)
2 tablespoons fermented sweet rice sauce (醪糟)
1 tablespoon sugar
1 tablespoon cooking wine
1 teaspoon minced ginger
2 scallions, chopped
dash of salt
(all of the above are available in
Soak raw sweet rice for 2-3 hours. After two hours of soaking, mix pork rib cubes with soy sauce, chili bean sauce, ground Chinese red pepper, fermented sweet rice sauce, minced ginger, sugar, cooking wine, half of the chopped scallions, salt and dash of water in a container. Set aside to marinate for ½ - 1 hour (but no longer). Peel and cube sweet potatoes.
When all the above are ready, drain the soaked sweet rice. Mix the sweet rice and marinated pork rib cubes until the meat is evenly coated with rice. Place this mix in the steamer, and lay sweet potato cubes on top of it. Steam on high heat for an hour or until rice and pork are cooked.
When serving, flip over the steamed content onto a plate, so that the sweet potatoes stay on the bottom. Top with cilantro and the remaining scallions.
