While the entire recipe is far too insanely complicated to repost here, it comes from the Momofuku cookbook.

The components are:

• steamed buns
• roasted pork belly (start with 3lbs skinless pork belly)
• scallions
• sweet pickles
• hoisin and siracha sauces

The candied crispies from the roasting of the pork make a fantastic condiment to the buns
