Instead of watching your yam spoil in the kitchen because you’re not ready to eat it that moment, here’s a better way to prevent your yam from spoiling. Peal it and cut into sizes of your choice. Put the quantity you know you will be able to consume in each ziplock and store them in your freezer. It can last for months in your freezer and the taste will still remain the same. The moment you bring it out from the freezer just put it straight on the fire. Please, this is only for those that always have light.
