Step 1

Cut onion into bite-sized pieces. Then place all of the onion pieces into an air-tight container (use a Tupperware with an airtight lid or a mason jar).

Step 2

Take out a small pot. Pour in the pickling ingredients. Bring up to boil.

Step 3

Once it comes to boil, turn it off immediately.

Step 4

While the soy sauce is hot, pour it in over the onions. It should be just enough liquid to cover the onions.

Step 5

Lock the lid and let the container sit at room temperature for 1 day.

Step 6

After 1 day, place the Tupperware into the refrigerator.

Step 7

Once chilled, it is ready to eat.
