This is a great way to use up the end of the garden, over-sized cucumbers. I started making these a couple of years ago and my family and friends love these. It is so nice to have fresh tasting cucumber salad in the middle of winter!
Slice cucumbers and onions into large bowl and mix. I use my mandolin and the thin slice blade to slice the cucumbers and onions. You do not need to peel the cucumbers first. I use my 13 quart stainless steel bowl to make this. Sprinkle with salt. Pour enough water over cucumbers and onions to just cover. I use nursery water, found in the baby food section for all of my canning as our water is too soft. Let set 2 hours. Drain in colander, but do not rinse. Put cucumbers and onions back in bowl.
Mix sugar and white vinegar and pour over cucumber - onion mixture. Stir and let set about 15 minutes. Put in freezer bags or containers and freeze. I usually put about 3 1/2 cups of the mixture into each quart bag. This recipe will make 10 quart bags. To use, thaw bag in refrigerator, pour into bowl and serve. Refrigerate leftovers. These stay crisp and taste just like fresh cucumber salad!
