Select even-sized medium to large cucumbers. Make sure they are not so big that the seeds get hard.
Peel and slice them thicker than for regular usage. Put them into a 2 cup sized freezer container or bag. Seal tightly and freeze at once.
Only do small batches of these in each bag.
When you want to use them, remove from the freezer and thaw until icy. Then, soak them in salt water for about a half an hour.
Drain, then add your cream, sugar, vinegar and freshly sliced onion if you like.
It sure does taste good in January, and it's a lot cheaper than buying from the stores.
