I ate the last of my 'Netty's Pride' bulbs today. They were sweeter tasting and I also believe a little less mealy after being stored in the refrigerator even for this relatively short time. It appears to me that even though these were prematurely harvested, the process of sugar production still got triggered, even in the refrigerator. Of course this is all very subjectively so take it for what it is
.
They were still very good, but sweeter isn't necessarily better for me in this instance as I basically have been eating them instead of potatoes. If they became much sweeter, I'd probably want a little less of them on the plate.
