Katsu sandoPork cutlet sandwich
Katsu sando began in Tokyo tonkatsu shops in the 1930s as a cutlet you could carry, and is now a fixture of department-store food halls, train-station kiosks and lunchboxes all over Japan: a crisp panko pork loin cutlet soaked in sweet-sour tonkatsu sauce between pillowy white bread, crusts trimmed off. The common mistake is slicing it while hot, which squashes the bread and makes it soggy; let it rest under a light weight first. Pork loin is a whole cut, so cook it to 63 °C and rest it for 3 minutes. Chef's tip: butter the bread with a little mustard mixed in; it stops the sauce soaking through and adds a gentle kick.
