If you have gluten or soy restrictions/allergies then this is a great soya sauce substitute. Coconut aminos can be used as a direct soya sauce substitute; it can be used in marinades, salad dressings, in soup bases, etc.
The brand I use is Coco Natura Coconut Marinade and buy it at Healthy Planet! Oh and btw, I highly recommend shopping at Healthy Planet because their prices are sooooooo much cheaper than the other health food stores that I frequent in Toronto.
Happy shopping!
