I made it in the wok and added a tbsp of sesame oil and a tbsp of ketjap manis (indonesian soy sauce) to the sauce. (bbcgoodfood.com)
No idea how it happened, but I tried to compensate by using: 1 tbsp sesame oil, 1 tbsp ketjap manis, 1 tbsp oyster sauce, 1/2 tbsp fish sauce. (howsweeteats.com)
THEN I discovered we were out of regular soy sauce and only had the thick and sweet ketjap manis soy sauce. (howsweeteats.com)
