The “Shu Ji” of my university here in China suggested the best brand for both Soy Sauce and Sesame Oil. Because she is the most powerful person in this highly respected university (Jinan Daxue) I’m willing to
take her advice.
Lee Kum Kee, which is a Cantonese translation of 李锦记, or in Mandarin “Li Jin Ji”. You can find it at your local Asian market or perhaps online. I’ll find a shop somewhere online and link it here later.
By the way, I’ve NEVER seen La Choy brand used in China. It’s probably just an American thing now… I know it wasn’t that yummy at stir fry night when I was growing up… Believe me, the brands of your seasoning matter.
