Spicy Soy Sauce Fish is a fiery twist on the classic recipe. In this version, red chili peppers or chili oil are added to the marinade to give the dish a spicy kick. The heat from the chili peppers complements the umami flavors of the soy sauce, creating a tantalizing combination of flavors. This dish is perfect for those who enjoy a bit of heat in their meals and can be served with steamed vegetables or a side of spicy noodles.
