Prepare two trays, one the 1 large egg beaten well, and the other with 100 grams panko. Prepare a wire rack lined with several sheets of paper towels to drain the pork katsu. Add 1 ½ inches of vegetable oil to a heavy-bottomed pot and heat the oil to 320° F (160° C).
1 large egg, 100 grams panko, vegetable oil
Season the 1000 grams pork rib chops with ½ teaspoon salt and white pepper and then dust them with 2 tablespoons all-purpose flour.

Dip the cutlets in the egg and coat evenly.
Transfer the pork to the tray with the panko and mound the breadcrumbs around the meat, pressing down gently on the cutlet to ensure you get a good coating of breadcrumbs on all sides.
Fry the Tonkatsu until golden brown, flipping every few minutes to ensure even browning. Use a skimmer to remove any foam that accumulates on the surface of the oil. Depending on how thick your katsu are, they should take about 10-15 minutes to cook through.
You can test if the pork cutlets are done by removing one from the oil and inserting an instant-read thermometer into the center. It should register 140 degrees F (63 C).
When the Tonkatsu is done, transfer the cutlets to the prepared wire rack to drain. Let it rest for 3 minutes before you cut it.
Slice the pork katsu and serve with Tonkatsu sauce and Japanese hot mustard.
