For Miso Sauce

  1. If you're making miso sauce as well or instead then take a small pan. Add 1 tbsp red miso paste, 1 tbsp honey, 1 tbsp sake, 1 tbsp mirin and 1 tbsp white sesame seeds.
  2. Turn on the heat (low) and stir continuously.
  3. Once thickened turn off the heat and set aside for later.

Fry the Katsu

  1. You can start heating your oil straight away. Using a deep pan or fryer, you want to heat the oil to 170°C (340°F).
  2. Next, prepare the katsu coating stations. In a dish, whisk one egg and prepare two separate plates, one with flour and one with the panko breadcrumbs. Three stations in total.
  3. First, coat the pork chops with flour on both sides.

  4. Next, dip them into the whisked egg.

  5. Then, press them into the panko breadcrumbs, make sure it's fully covered.

  6. Check your oil is hot enough, either with a thermometer or drop a piece of panko in. If the crumb sizzles and floats, you're ready to go!
  7. Carefully place the coated pork chops into the oil and cook for about 4 minutes on each side (8 minutes total) or until golden brown.

  8. While the katsu is cooking, finely shred your cabbage (as fine as you can!) and cut the crusts off of your bread pieces. (Cutting the crusts is an optional step but katsu sando you see in Japan nearly always has crusts cut off!)
  9. When the oil stops making a crackling sound, that means the tonkatsu are ready. Set on a wire rack to let any excess oil drain off.

Katsu Sando is usually made with plain white bread, but of course you can use your preferred bread. It is also usually served with the bread crusts cut off, but it's up to you if you want to keep them on.

Try not to touch or move the tonkatsu during the first minute of frying otherwise the breadcrumbs may start to fall off.
