I used to grate the zucchini and put it in 1 or 3 cup quantities in freezer bags and store them in the freezer. You could do the same thing with the dry ingredients and then just throw it altogether with eggs and oil(?) and bake whenever you want.
Our working freezers are already full. We did freeze some in 2010, but lost them due to freezer malfunction, hence the search for something else to do with them.
We have gradually been winding down our electricity useage. So far we have reduced our bill by 10-30% per year for the last 3 years.
Since drying takes up less space and electricity, It’s on par with home canning these days.
Great Idea, thank you.
