I blanch, cut from the cob, and freeze my own corn in a vac bag with a pat of frozen butter(keeps it from ending up in the food saver). Take a bag out, drop in simmering water and nice hot as close to corn on the cob as you can get.
I think it is the lack of taste with zucchini, one of the most bland things I have ever eaten. Around here people end up trying to give them away, you don't leave your car unlocked or you might find a bag of them in your front seat
The Kitchen Aid grain mill is not known for working well to create a fine flour. That is something to look into also. Impact mills will make very fine flour but miss a stone or anything hard and it destroys them.
