Every southern family has this in their refrigerator in the summer. And I mean EVERYONE.
In a large jar, add about 2 cucumbers (depending on size) sliced – not paper thin, but like bread and butter pickles and 1 purple onion cut in wedges and separated. Peel your cucumber or run a peeler down the sides for a stripe.
Alternate the cucumbers and onions until the jar is full. Fill jar with water and vinegar 2:1 ratio. You can use apple cider vinegar if you want, but I use white vinegar. Add a pinch of sugar and salt and pepper to taste. I would start with ½ teaspoon salt and ½ teaspoon pepper. Put the top on tight, shake it up, and refrigerate. In 30 minutes, open it and taste, if too salty, pour a little liquid out and replace with water, if not salty enough, add a little salt.
You serve this right out of the jar with EVERYTHING. Especially great with fresh vegetables. So refreshing! Will keep for days in the frig – that is if it lasts that long.
