Mix 2cups of water, 4tbsp soy sauce, all minced garlic and all sliced onions, 3tbsp brown sugar, chili pepper and 2 tbsp of rice wine together, and boil it over medium low heat for 20 mins.
Chop beef into small pieces
Put everything together into pressure cooker and have it cooking for 35mins(something like that).
After pressure cooker, take out the pot and add corn syrup, sesame oil. This time we can either heat it up with high heat and let the syrup melt or use the pressure cooker again.
This time I forgot to put green onion and Chinese mushroom, but they will highlight the dish better I'm sure.
