Insert a matches stick into yam and it will stay longer without spoiling.
In a Post shared by Kofi Asare it says:
Got home at midnight, worked a bit more and slept only a few hours this dawn.
Hungry; I am cooking my yam breakfast. The last yam meal was a fortnight ago.
I inserted the matches stick into this yam six weeks ago. This is my third and last eat. It’s still fresh.
I learnt this when i was doing my national service.
Stop freezing Yam.
Insert to preserve!
