This is the most popular tonkatsu recipe in my family. You'll gobble the sweet sesame-miso sauce with rice.
I cooked soft tonkatsu, and it was more delicious than I had imagined, so my family stuck with this recipe.
If you so happen to buy meat that is too lean, then you can stick in sliced beef fat between the meat, and it will turn out nicely. My family always keep beef fat in the freezer.
Enjoy Japanese food around the world.
