If anyone is interested in the Marinade i use for the chicken thighs or pork its this:
1/4 cup sugar
4 TBSP mirin
1/4 tsp garlic powder
1/2 tsp garam masala
1/4 tsp white pepper
2 tsp oyster sauce
2 tsp sweet soy sauce (abc)
1 tsp soybean/sesame oil
4 TBSP bull head bbq sauce
4 TBSP teryaki sauce
Thats for about 2lbs of chicken thighs or pork.
I use a vacuum tumbler @ 30 psi for 30 minutes, but you could just marinate for 4+ hours.
PS: you could probably sub the oyster sauce and the sweet soy sauce for Hoisin sauce, but im not a fan of hoisin sauce so thats why i used oyster and sweet soy.
FYI: The bull head bbq sauce is imo the star of the show, Its so thick you have to dilute it to work as a marinade. Hense, all the other ingredients. LOL
