Gochujang, the popular Korean condiment, is the secret sauce behind this Korean spicy pork. Rubbed all over the meat before smoking, the fermented chili paste adds sweet, spicy, and savory notes. Serve up this gochujang pulled pork in a lettuce wrap, on a bun, or over rice. Note: You can use either gochujang paste or sauce, which includes vinegar as well as a few other ingredients and has a looser consistency.
