For the tonkatsu sauce: Combine the ketchup, honey, jam, soy sauce, vinegar and Worcestershire in a small bowl and stir to mix together.
For the karashi mayonnaise: Combine the mayonnaise, mustard and orange zest and stir to mix together.
For the chicken or pork katsu: Arrange 3 shallow bowls or pans. In the first put the flour, seasoning with salt and pepper. In the second, add the eggs and whisk for 1 minute. In the third, mix together the panko, cornstarch and salt and pepper.
Lay the cutlets first in the flour, dusting off any excess. Next, dredge the cutlets in the egg, again allowing the excess egg to drip away. Finally, dredge the cutlet in the panko-cornstarch mixture, applying a bit of pressure on the meat to ensure the breading sticks properly. Place on a baking sheet or platter and let sit for 5 minutes.
In a large saute pan, heat the butter over medium heat until bubbles start to appear. Add the cutlets and pan fry until golden brown and crispy, 3 to 4 minutes per side.
Spread half the bread slices with the tonkatsu sauce and karashi mayonnaise. Top with some cabbage, a cutlet and the remaining bread and chow down!
