Ohhhhhh yes, you can freeze them..
I use a Salad Shooter type machine with
the cheese shredder funnel on it, and
stuff in the desired zuke and do them into
ziplock freezer bags ****I roll down the sides, first, so that when I salad shoot them in, the zipper parts don't get wet or dripped on****
(Or to be on the safe side, MEASURE THEN INTO A CUP MEASURING CUP, then plop that into the sandwich baggies..)
Then squish a bit of air out, flatten a bit..
and lay flat in the freeze *a cookie sheet works great to put them in first if you have a big freezer*
When you go to use them in the middle of winter for a zucchini bread or something..
Get a sieve/strainer/collander and let the baggie sit...
It'll thaw.. and when it's thawed, dump it into the sieve/strainer/collander and LET THE WATER *from freezing* drain...
Then use as according to the recipe......
