Thank goodness for one of my favorite books this time of year, The Busy Person's Guide to Preserving Food by Janet Chadwick. She actually has a recipe for freezing cucumbers, which I decided to try this year. I'm sharing her method for preparing them below, which reminds me of the method I use to make Japanese salt pickles:
Freezing Cucumber Slices
Take two quarts (8 cups) of thinly sliced cucumbers and 1 thinly sliced medium onion and combine with two tablespoons salt in a colander. Place the colander in a bowl and let stand two hours to drain moisture from the cucumbers. Wash and drain the mixture, then wash and drain it a second time to remove all the salt.
In a large bowl, combine the cucumbers and onion with 2/3 cup each of sugar, vinegar and oil and 1 teaspoon of celery seed. Let stand one full day in refrigerator. The package the cumbers in containers leaving 1 inch of head space and freeze.
Enjoy them after one week in the freezer. Once defrosted, they will be good for several weeks in the refrigerator.
