I keep a few soy sauces on hand, but Kikkoman is my go to.
I use a few jugs of that each year just when making jerky.
Yamaroku make a traditional barrel aged one that makes a great finishing/dipping sauce. It's also da bomb on ice cream.
It's 5 to 10 times the price of Kikkoman , but is well worth it.
Avoid chemical soy sauces. Check for that if you are buying store brands.
Buying quality stocks is the best get-rich-slow scheme. It’s not sexy as a get-rich-quick scheme,
but the probabilities of success are greater.
Remember........ It's better to wish you had bought a
stock, than to wish you hadn't.
