Ingredients

- 2 tsp Kosher salt: Salt enhances the flavor and helps preserve the onions.

These basic ingredients can be transformed into a flavor explosion.

- Then heat the mixture to a boil while stirring until the salt and sugar is dissolved
Adding the brine to the the onions
- Pour the hot pickling liquid over the onions, ensuring they are completely submerged. We want to completely submerge the onions to ensure all of it is pickled and for there to be less chance of other bacteria to grow.
- Then center the lid over the jar while it’s still hot. Add the lid ring and tighten once it’s cooled off
