Okinawa Shoyu Pork
I think the Okinawans got the slow food concept right on - this was one of my favorite dishes growing up...shoyu pork...eaten over rice, or on top of soba. The soy sauce-marinated, slow-cooked pork with just the right amount of sweet taste (imagine Okinawan brown sugar) is pretty close to perfect...
It's best to use pork belly, but pork tenderloin or boneless pork short ribs are also great.
You can substitute 1/2 cup water for katsuo dashi. Katsuo dashi is a fish stock made from water and bonito flakes. In a small pot, boil 1-2 c of water and about 1/2 c bonito flakes for a few minutes. Pour into a bowl, straining the bonito flakes out of the liquid so you have only stock.
