The sauce for the Menchi Katsu Sando is curry made from spices. The topping is homemade fukujinzuke pickles. From skewers to sandwiches, the Katsu has changed its form and is now taking on the world! Many of the katsusandos that are now popular in Europe and the United States were created by local chefs who were influenced by Japanese fried pork cutlets and katsu sandwiches. Kushikatsu Tanaka, which has spread kushikatsu culture in Japan, cannot afford to lose to a foreign country in its specialty, katsu.   The sauce for the cutlet sandwiches at TANAKA, which opened in the U.S., is based on a recipe that has been a favorite at Kushikatsu Tanaka for many years and is reproduced using plant-based ingredients, with no chemical seasonings, to make it vegan-friendly. The bread crumbs used for the cutlets are also made from homemade bread. In addition to pork, several types of sandwiches are available, including chicken, fish, beef, and even vegan sandwiches, to meet the needs of the overseas katsu sando market. Also, unlike kushikatsu, the sandwiches are suitable for take-out or one-handed eating outside, which would be in line with Western food culture. Can Japanese katsu sandwiches really compete with katsu sando in the West? We will keep our eyes on this new challenge by Kushikatsu Tanaka.
