Place some neutral oil into a wok or frying pan.
Once the oil is hot, place-in the chicken pieces - skin-side facing down.
Set heat to medium. Give the chicken pieces a few minutes to cook away, so the skin can release its oil and create good flavor.
(Optional: After a few minutes, add in the garlic slices)
After you get some browning on one-side, flip each chicken piece over and cook on the other side.
After a few minutes, add in the Korean radish pieces.
Stir-fry the chicken & radish together for a few minutes - or until the radish starts to sweat.
Once the radish pieces start to turn translucent and get slight browning, add in the Hot Mustard (1 teaspoon).
Then add-in Soy Sauce (1 Tablespoon). Add in a circular motion around the pan wall. This way the soy sauce can heat-up and develop a deeper flavor.
Now stir-fry everything for 30 seconds ... or until everything is well mixed!
Scoop the delicious ingredients over a bowl of freshly made rice.
(Optional: You can add a dab of the hot mustard as a topping on the bowl)
Bon Appetit!
