All-Purpose Soy Sauce

Clean and thinly slice the green onions and onion.

In a pot, add soy sauce, water, cooking wine, sugar, green onion, onion, garlic, and kelp.

Bring the ingredients to a boil over medium heat.

Once it starts to boil, reduce to low heat and simmer for 10 more minutes.

Remove the kelp first, then strain the remaining ingredients, leaving only the all-purpose soy sauce.

Let it cool completely, transfer to a container, and store in the refrigerator.
