Step 1: Put sliced cucumbers, onions, and salt into a large bowl and toss well. Add 3 cups ice cubes, cover bowl with plastic wrap, and refrigerate overnight.
Step 2: Drain cucumbers and onions well, discarding the salty water; set aside.
Step 3: Put vinegar, sugar, mustard seeds, celery seeds, and turmeric into a large pot, stir well, and bring to a boil over medium-high heat. Add the cucumber–onion mixture and stir well. Allow liquid to return just to a boil, then remove pot from heat. Transfer pickles and their liquid to a large, clean plastic container. Set aside to let cool to room temperature, then cover and refrigerate overnight.
Step 4: Serve pickles the next day or store for up to 1 week.
