I did it last night. Made about 4 ponds of rice, 2 ponds of meat (pork belly) ---- 2/3 with meat; 1/3 just rice. Kids do not like me adding more stuff (such as egg yolk, peanuts...) in.
A bag of leaves can be used for several years. I usually also pick up some LUWEI (very small) leaves from the local stream and add then inside of banboo leaves.
That is the way my mother did---- she does not know how to wrap. We had it that way for a year after my grandma passed away. Later, my father learned to make them..........
