Cut up the pork belly slices, and marinate in the soy sauce, sake, grated ginger, salt and pepper. Stir-fry the pork until it gets brown.
Grate the daikon radish.
Finely shred the cabbage. (Try to shred it as finely as possible, and it will be much nicer to eat.)
Chop the green onion.
Put some hot rice in large serving bowls.
Mound the shredded cabbage on top of the rice.
Put the cooked pork on top of the cabbage. It already looks yummy!
Add some grated radish on top of the meat.
Add the chopped green onion, pour the ponzu sauce over and it's done.
Story Behind this Recipe
The usual sweet-salty sauce is great but sometimes you want to eat something refreshing with vinegar. I had a delicius pork donburi once with ponzu sauce once, so I tried making it myself. It's so light that you end up eating quite a lot of rice with it.
Shred the cabbage finely. I save time by using grated daikon radish and ponzu sauce.
