Ube Halaya

My mother taught this recipe to me.

Ingredients:

1 kilo ube yam root
1 can evaporated milk
2 cans condensed milk
1 Anchor butter
1 cup sugar if needed
food coloring (blue)

Boil unpeeled ube yam in water and simmer for 30 minutes. Drain and cool. Peel and finely grate the ube yam. Heat a big Wok and place the condensed milk, evaporated milk and the grated ube yam. Keep on mixing the ingredients until sticky and add the Anchor butter. Add a little food coloring to make it a little blue in color. Mix until a little bit dry. Taste and add sugar if needed. When done, let it cool a bit and place in containers. You may spread additional butter on top of the yam before serving.
