Soy sauce has become such a common ingredient but do you know which one to buy and why? Kikkoman brand is one of the best. A lot of their soy sauce is now manufactured in Singapore. There is a subtle taste difference but cheaper.
I have tried many soy sauce to replicate the true authentic Asian cooking at home. This is still my preferred one - Kikkoman's Special Blend (Tokusen Marudaizu Shoyu).
