(follow-up on a conversation with Pia)
At a Filipino bakery today I bought something called Pitche Pitche Penipig -- rectangular slices of somewhat glutenous/gelatinous (a word that completely escaped me earlier) substance, instensely purple, topped with toasted coconut. The ingredients are penipig, sweet rice, coconut milk, milk and sugar.
Unfortunately I didn't get to try it; however, my dog (who stole it out of the bag but left the other stuff) really seemed to enjoy it.
Any idea as to what "penipig" is? I'm assuming it's some sort of taro-like root.
