Vegetables: I julienned carrot (one small) and celery (two stalks) in a slightly larger than match stick size. I also sliced Vidalia onion (1/2, medium). I like my vegetables to be "cured" so I added and soaked the vegetables several hours at room temperature in sweet vinegar in a sealed container.Frying: I removed the excess sake on the fish filetts using a paper towel and dredged them in potato starch or "katakuriko" 片栗粉. I deep fried the fish in 170F or 340C vegetable oil for several minutes on both sides. I drained the excess oil by resting the fish on a wire rack (I use a small frying pan with just half inch of oil. I will not reuse this oil since the sardines make it taste "fishy").
Meanwhile, I removed the vegetables from the sweet vinegar and arranged them on two plates (#4 above). While hot, I soaked the fillets in the sweet vinegar and turned them over several times to coat nicely (#3 above). I placed the fillets over the vegetables and garnished them with finely julienned ginger and perilla leaves (#4).
It turned out that the red pepper I used (bought it in a Japanese grocery store) was atomically hot. Especially the vegetables got really spicy. The fish was nicely crunchy with a sweet vinegar taste. No need to worry about bones because of the preparation I did. For me, the spiciness was the higher boundary of "OK" but, for my wife, it was too much especially for the vegetables but she finished the fish with gusto. the only drink we can think of is cold sake for this dish.
