Tonkatsu Sando (とんかつサンド, pork cutlet sandwich)

Ingredients

Equipment Needed

• •Heavy pot or high-sided frying pan for frying
• •Kitchen thermometer
• •Abura-kiri oil-draining rack, or a wire rack set over a tray
• •Japanese cabbage slicer, or a mandoline used carefully

Instructions

1. 1

   Dry the cabbage

   Shred the cabbage as finely as you can, rinse it briefly in cold water, then drain and dry it very well in a spinner or clean towel. The rinse freshens the cut edges, but any water left behind will go straight into the bread. For this sandwich, dry cabbage is not a small detail. It is the difference between crisp and tired.

2. 2

   Level the pork

   Score the strip of fat along each pork cutlet in a few places, then tap the meat gently until it is an even thickness. Season both sides with the salt and white pepper. Scoring keeps the fat from pulling the cutlet into a curve as it fries, and even thickness lets the pork cook through before the panko grows too dark.

   Choose pork that looks rosy and fresh, with clean white fat. No sauce will rescue pork that smells sour or looks gray. Nothing hidden.
3. 3

   Bread the cutlets

   Set out flour, beaten eggs, and panko in three shallow trays. Coat each cutlet lightly in flour and shake off the excess, dip it in egg, then press it into the panko so the crumbs cling in an even layer. Let the breaded cutlets rest for 10 minutes while the oil heats. The flour gives the egg something to hold, the egg gives the panko something to hold, and the short rest keeps the coating from shedding in the pot.

4. 4

   Fry the tonkatsu

   Heat 5cm of neutral oil in a heavy pot to 170 C. Fry two cutlets at a time, about 3 minutes per side, until the panko is deep golden and the pork reaches 63 C in the center. Keep the oil steady, not furious. If the heat drops too far, the crust drinks oil; if it climbs too high, the crumb browns before the pork is done.

   A wire rack is better than paper towels here. Paper traps moisture underneath, while a rack lets the cutlet stay crisp on both sides.
5. 5

   Rest and sauce

   Move the fried cutlets to a rack and rest them for 5 minutes. Brush both sides with tonkatsu sauce, using enough to gloss the crust without soaking it. Resting lets the juices settle and gives the crust a moment to firm; saucing too heavily turns the panko soft before it reaches the bread.

6. 6

   Build the sando

   Stir the softened butter with the karashi, if using, and spread a very thin layer on one side of each slice of shokupan. Lay a small bed of dry shredded cabbage on 4 slices, set one sauced cutlet on each, add a little more cabbage, and close with the remaining bread. The butter is not there to make the sandwich rich. It is a thin barrier, keeping sauce and cabbage from soaking the bread too quickly.

7. 7

   Press and cut

   Set a light board or tray over the sandwiches for 3 to 5 minutes, just enough to settle the layers. Trim the crusts if you want the classic shop look, then cut each sandwich into three fingers with a sharp knife, wiping the blade between cuts. That clean face is part of the dish. Leave it ragged and you've worked hard only to hide the evidence.

Chef Tips

• •Ask for pork loin cutlets of even thickness, not thick chops. A sandwich wants balance. Too much pork and the shokupan disappears, which is a strange way to honor good bread.
• •Use Japanese shokupan if you can. Its fine crumb and gentle sweetness are not decoration; they hold the cutlet without fighting it. Soft square milk bread is the sensible stand-in.
• •Bottled Japanese tonkatsu sauce is proper here. Use it with restraint. The sauce should season the pork, not turn the sandwich into a bowl.
• •If you pack this for a picnic, let the cutlet cool to warm before assembly, wrap the finished sando in parchment, and eat it the same day. Keep it chilled if it will sit more than two hours.

Advance Preparation

• •The cabbage can be shredded, rinsed, dried thoroughly, and refrigerated in a covered container for up to 1 day.
• •The pork can be breaded up to 2 hours ahead and kept uncovered on a rack in the refrigerator. Fry it close to serving so the panko stays crisp.
• •Assembled sandwiches hold for about 30 minutes at room temperature for serving. Longer storage softens the bread and dulls the crust.
