Ube Piaya or Purple Yam Pie. This was the pasalubong from one of our consultants, Sir Llowen, who spent their Christmas vacation in Bacolod City, Philippines. I like this because it is soft and chewy unlike other locally made Ube Piaya sold in the market here in Davao City. Thank you Sir. It's really yummy and delicious!
