Pork Kimchi Stir Fry

Ingredients:

• ½ lb thinly-sliced pork belly (you can slice a block of pork belly on your own; you also may use thinly sliced pork loin)
• ⅛ tsp freshly ground black pepper
• ⅛ tsp kosher salt (Diamond Crystal; use half for table salt)
• ½ lb kimchi (use Fresh Kimchi or traditional fermented kimchi; roughly 1½ cups for 2 servings)
• ½ onion (143 g, 5 oz for 2 servings)
• 2 green onions/scallions
• 1 Tbsp neutral-flavored oil (vegetable, rice bran, canola, etc.)

For the Seasonings

• 1 Tbsp sake (sake helps to remove the pork's gamey odor; you also can use Chinese rice wine or dry sherry, or otherwise, skip it)
• 1 Tbsp kimchi juice (it's the juice from the kimchi jar)
• 2 tsp soy sauce
• 1 tsp roasted sesame oil
