In a big bowl, mix all the moo dang marinade ingredients like smashed garlic and coriander, palm sugar, white pepper, 5-spice, soy sauce, oyster sauce, sesame oil, tapioca starch, and red food coloring. Stir it until the palm sugar melts away. Toss in your pork and get it all covered in the red sauce. Wrap the bowl with cling film and keep it in the fridge to marinate for at least 24 hours. Don’t toss the marinade after, you’ll need it!
