How to Make Katsu Sando
Prepare the Pork: Cut the pork tenderloin in half, then slice each piece lengthwise and gently flatten to ensure even cooking. Aim for a thickness of about 1.5-2 cm.
Tenderize: Use the back of a knife to lightly pound the pork, creating a rough surface. This helps to tenderize the meat, ensuring it s juicy after frying.
Season and Freeze: Sprinkle a pinch of salt and pepper on both sides of the pork. Wrap in plastic wrap and freeze for 30 minutes to 1 hour to firm up.
Make the Mayonnaise: In a small bowl, combine Japanese mayonnaise, mustard, sugar, and a pinch of black pepper. Mix well and set aside for maximum flavor infusion.
Prepare the Miso Sauce: In a small pan, mix red miso, light brown sugar, sake, mirin, dashi stock, and soy sauce. Heat on low until the sauce thickens, then fold in toasted sesame seeds.
Heat the Oil: Get your frying pan ready! Heat cooking oil to 160 °C (320 °F) for the first fry, ensuring a crispy katsu.
Breading Station: In a bowl, whisk the egg with milk and oil. Set up separate plates for all-purpose flour and panko breadcrumbs to streamline your breading process.
Coat the Pork: Unwrap the pork from the freezer. First, coat it in flour, shaking off any excess. Then dip it in the egg mixture, followed by a generous layer of panko breadcrumbs for that signature crunch.
Fry the Katsu: Deep fry the pork cutlets for 4 minutes on each side until golden brown. Transfer to a wire rack to rest for 5 minutes and maintain that crispy texture.
Second Fry: Increase the oil temperature to 180 °C (356 °F) and fry each cutlet for 1 additional minute on each side for an extra crunch.
Add Flavor: Transfer the katsu to a wire rack and drizzle Worcestershire sauce over both sides. This adds a delightful tang to each bite.
Assemble the Sandwich: Spread butter on one side of each bread slice. Layer with the miso sauce, shredded cabbage, and katsu. Close the sandwich, trim excess, and cut in half before serving.
Optional: Serve with pickled vegetables for a pop of color and flavor!
