Thanks for the input, zeebee. The one recipe I found online that recommended going straight from frozen to water to breading to fryer also mentioned that you can do the first three steps, and save breaded zucchini slices still frozen, in a plastic bag or container in the freezer, to have ready whenever you want to fry a few.
So far I think the frozen-to-fryer approach ought to be okay, but if I want to really study the matter, for my own sake and whoever else is curious, I'll need to try at least the following options and compare:
a) fresh slices fried
b) frozen slices fried
c) frozen slices thawed and fried
Sounds like the kind of experiment Cooks Illustrated would already have done, doesn't it? Alas, no, not that I could find on the CI website. For that matter, there's a mysterious dearth of recipes for fried things on the CI website. Surely they have one for chicken at least.
As for why I have these frozen zucchini slices? I, yes, BOUGHT them, frozen, in a bag, for 88 cents, just so I could learn how to deep fry them. But a little googling has shown me that gardeners all over the country have tons of leftover home-grown zucchini in their freezers and are desperate for ideas for what to do with it. Apparently one can only stand to eat so much zucchini bread in one winter.
