• Add all brine ingredients to the small saucepan and stir until the sugar and salt dissolve.
• Heat your brine until it is lightly simmering.

While your brine is heating, thinly slice your onions.

• Cut your onion in half from root to stem.
• With the center of your onion flat on the cutting board, cut the onion beginning at the stem side and moving toward the root end in as thin of slices as you can.
• After cutting the onions, you should have slices that resemble a rainbow or half circle.
• When all your onions are sliced, break apart the layers and add the slices to your glass jar being sure to pack them in tightly.
• After your brine is come to a simmer, remove from the heat and add the hot brine to your prepared jar until all onions are covered. Remove any bubbles from your jar with a small silicone scraper or small wooden spoon.
