Butajiru is a simple Japanese miso soup elevated with tender pork slices and a variety of vegetables. The base of the soup is a hearty miso broth which incorporates water or dashi stock infused with the fragrant miso paste. Numerous vegetables are added to butajiru, but the most traditional options include typical Japanese root vegetables such as daikon, carrots, taro roots, and the slightly sweet gobo root.
Common additions can also incorporate the gelatinous konnyaku, ginger, tofu, and scallions, but the choice of elements can be adjusted according to personal preferences. All ingredients are thinly cut and sliced in order to ensure fast and convenient preparation.
