The meat holds moisture in spades, and the cheese imparts its expected extra flavour. There are no surprises here, only satisfaction.
Between this and the yuzu version, I lean a little more into this for the flavour that the cheese lends.
However... I will go back just to try the Tsukune without any sauces or toppings, just Okinawa salt, to see how the beef holds up by itself.

Special Thanks to @foodinsing for spoiling us with this treat and @aburiyasg for taking good care of us!
