I have never tried Ochazuke, butI think I like all of the "Leftover" cuisines. Foods where ingenuity finds a way to re-use foods from the previous nights dinner.
My two all time favourites are Pad Thai and Pizza. With Pad Thai, you throw your leftovers into noodles, then refry them, with pizza, you throw your leftovers on some bread dough and bake it.
Using tea on the rice is a nice twist. That would add some nice floral notes.
Yep it tastes fantastic
