Any good brands you would recommend?
Yamasa is great..and they have been around since 1645...they must be doing something right.
Yamasa has been recommended to me by several Sushi chefs, and several Asian Market vendors...reasonably priced and high quality...
Go for the Low Sodium Soy...full of flavor and character, and you can always add more salt if you want...
Their Terryaki sauce rocks too...
When in doubt find the nearest Asian Market, and go talk to its proprietor...as him or her what they use at home when cooking for their family...
