Step 1

Prepare teriyaki sauce by mixing soy sauce, mirin, and sugar in a cup. Pour the mixture into a saucepan, and bring it to a boil. Keep stirring the sauce until the sugar has dissolved. Turn off the heat and set aside.

Step 2

Cut ribs apart and place them in an Instant Pot (or a slow cooker). Evenly sprinkle ground black pepper on top and add 2/3 of the teriyaki sauce. Cover the pot and cook for 30 minutes in an Instant Pot or 4 hours on high in a slow cooker.

Step 3

Simmer the remaining teriyaki sauce with Balsamic vinegar and garlic for 5 minutes on medium heat. Turn off the heat and transfer to a dish.

Step 4

Brush sauce on cooked ribs and garnish with white sesame seeds before serving.

Step 5

Serve slow cooker teriyaki ribs with slaw, green salad, or steamed rice.
