Trim both ends of the onion, leaving the root end intact. Peel the onion and slice it in half from the stem end to the root end. Use a mandoline (2 mm blade) or knife to thinly slice the onion. (See Tip 1)
Add sliced onions to a 12-ounce mason jar. Pour hot brine over the onions until fully submerged. (See Tip 2)

Tips/Notes
I ended up with about 1 ¼ cups of thinly sliced onions.
Although the 12-ounce jar holds just 1½ cups, the onions compress and the brine fills the gaps. Using 1 cup of liquid is just right. There is no overflow and no waste.
