One of my favorite merienda is the nilupak. It's made of kamoteng kahoy (yucca root or cassava), sometimes kamote (sweet potato), at other times saba (a form of banana used for cooking), mashed until it's smooth, with sugar to taste (and sometimes milk). The result is laden with butter or margarine. This is at times wrapped in banana leaf for packaging.
When I was a kid, we usually do the manual task of making this delicacy using banana or saging na saba. We usually borrow "lusong" to our neighbor that time, the one they use in grinding coffee. It's quite a task preparing this food, from cooking the banana to grinding it. But the result is one of the best. Add some margarine, sugar and coconut on top.....you'll surelly love it too.
