Instructions
Cook the rice: Combine Japanese short-grain rice and water in a rice cooker (or pot), then cook until tender; keep warm.
Make a seasoning mix: In a small bowl, combine the kosher salt and black pepper; set aside, reserving about half for the curry and half for the pork and dredge.
Start the curry base: Melt unsalted butter in a wide pot over medium-low heat. Add onion and cook, stirring often, until deep golden and jammy, 18–22 minutes.
Add carrot, garlic, and fresh ginger; cook until fragrant and the carrot softens, 2–3 minutes.
Stir in tomato paste and cook until slightly darkened, about 1 minute.
Sprinkle in the all-purpose flour (for curry roux) and curry powder. Cook, stirring, until the flour smells toasty, 1–2 minutes.
Gradually whisk in chicken stock until smooth. Add apple, soy sauce, Worcestershire sauce, and about half of the reserved seasoning. Simmer uncovered, stirring occasionally, until thick enough to coat a spoon, 15–20 minutes.
Blend the sauce smooth with an immersion blender (or carefully in a countertop blender), then return to a gentle simmer. Stir in garam masala and simmer 2 minutes more; adjust thickness with a splash of stock if needed. Keep warm over low heat.
Prepare the katsu: Place the all-purpose flour (for dredging) in a shallow dish, the eggs in a second dish, and the panko breadcrumbs in a third. Pat dry the boneless pork loin chops, sprinkle both sides with some of the remaining reserved seasoning, then dredge in flour, dip in eggs, and press into panko to coat; rest the breaded cutlets 5 minutes.
Heat the neutral oil in a large, heavy skillet to 350°F/175°C. Fry cutlets in batches, turning once, until deeply golden and cooked through (145°F/63°C), 4–5 minutes per side. Drain on a wire rack.
Slice the katsu crosswise into strips.
To serve, mound the cooked rice in bowls, ladle on curry sauce, and top with sliced katsu. Add fukujinzuke pickles as desired (for serving).
