It's my first time to eat Dried Sapsap, a product bought by my pinsan in Palawan. Compare to other dried sea-foods I have tried like tuyo this one is a crispier and tastier. It compliments vinegar with garlic and chili sauce with hot plain rice. I highly recommend you to try dried sapsap. I bet, you won't regret the experience.
(sorry for the low quality)
PS: I am not sure if it's available in Manila.
