A few months ago, while at the night market, my sister decided to buy some Ube (or Purple Yam) and make Ube jam. Without knowing how to properly make it, I volunteered to work it in the kitchen with some ideas in mind.
What I did was: peel the skin, grate them to small pieces as much as possible so it will be easier and faster to melt, put them in a hot pan, add a can of condensed milk (depends on how much ube you have), and keep stirring until it has a jam-like texture. I even added some pinch of salt for taste. It actually turned out great~ as what everyone at home said so.
Here's my scoop of Ube jam (and my failure attempt at making it less boring, lol). :D
