The ingredients for the Kong Piah are flour, yeast, alkaline water and water. The big dough is then divided into smaller portion and filled with fillings such as minced pork, onions or just plain sugar. They are then placed in a special made charcoal oven to be baked for 10-15 minutes. They are best eaten when just cooked but many will tapau them back home and place them in freezers to be kept for weeks. Of course, it has to be reheated first before eating.
I don't know how it tastes like as it contains pork or is made with lard.
