Packing the Ingredients into a Jar
Use a sterilized glass jar to prevent contamination and ensure a clean fermentation process.
Layer the onions, garlic slices, and chili peppers (if using) into the jar.
Pour the cooled brine over the onions, ensuring they are completely submerged.
Place a small weight or a clean plate inside the jar to keep onions below the liquid level, preventing mold growth.
