Sweet Refrigerator Pickles

Step 1
Mix cucumber slices and salt together in a bowl; let sit for 1 1/2 hours.

Step 2
Pour cucumbers into a sieve set in the sink. Thoroughly rinse cucumbers under cold running water and drain well.

Step 3
Combine white sugar, white wine vinegar, apple cider vinegar, brown sugar, mustard seeds, celery seeds, and turmeric in a saucepan over medium heat. Bring to a boil, then cook and stir until sugar dissolves, about 3 minutes.

Step 4
Place drained cucumbers into a heat-proof bowl. Add onion, then pour hot vinegar mixture over top. Let stand at room temperature for 1 hour.

Step 5
Transfer cucumbers and liquid to a container with a tight-fitting lid. Cover and refrigerate for 24 hours before eating.
