My meaning was misread, so I'm sorry that I wasn't more clear.

Nido on the counter should be used fairly quickly after opening. I anticipate it will last longer in the refrigerator. My opened but covered can that sat near the stove went bad over time. (I use the microwave more than the stove, unless backpacking. When we find ultra light long cords and microweight microwave ovens, that could change...maybe.)
