Katsu Sando

Japan

Katsu sando was invented in 1935 by Isen, a tonkatsu restaurant in Tokyo's Ueno district, just five years after it first opened. It later found a second life in Japan's convenience stores and train station bento counters, and more recently became a genuine international trend, popping up on menus from London to New York.

A golden, panko-crusted pork cutlet pressed between soft, crustless white bread with sweet-savoury tonkatsu sauce — Japan's most elegant convenience-store sandwich.

Ingredients

2pork loin cutlets, about 2cm thick
3 tbspplain flour
1egg, beaten
100gpanko breadcrumbs
for fryingneutral oil
4 slicessoft white sandwich bread, crusts removed
2 tbspsoftened butter
4 tbsptonkatsu sauce
1 tspJapanese mustard (karashi), optional

Method

1

Season pork cutlets with salt and pepper. Pound gently to an even thickness if needed.

2

Coat each cutlet in flour, then beaten egg, then press firmly into panko until fully covered.

3

Heat 2cm of oil in a pan to 170°C. Fry cutlets 3-4 minutes per side until deep golden and cooked through.

4

Drain on a rack for a few minutes — this keeps the crust crisp rather than soggy.

5

Butter each slice of bread. Spread mustard on two slices if using.

6

Spoon tonkatsu sauce generously over the cutlets on both sides.

7

Sandwich each cutlet between two slices of bread, pressing down firmly.

8

Rest for 2 minutes, then slice cleanly in half or thirds with a sharp serrated knife.

Chef's Tip

Rest the assembled sandwich for a couple of minutes before slicing — this lets the crust settle slightly so it doesn't shatter and fall apart under the knife.
