[What is suridane in the first place? ? Suridane is an all-purpose seasoning that originated in Fujiyoshida and is based on red chili pepper with sesame and Japanese pepper. I always have it when I go to Yoshida's udon and hoto shops in Fujiyoshida and Kawaguchiko. Generally speaking, we think of ichimi and shichimi as the spiciness of udon, but here in Fujiyoshida and Kawaguchiko Yoshida's udon, we use suridane instead of ichimi and shichimi. Suridane is also called “Karami” or “Spicy” and is placed on counters and tables in the same way as tenkasu and soy sauce. It's not just spicy, but the umami is condensed into the spiciness. Common suridane is often moist, but the way it is made varies depending on the shop, so they have established their own unique taste by stir-frying in oil, adding soy sauce, sugar, and dried bonito flakes. increase. Super Spicy Takana-sensei's suridane is a completely original recipe that mixes [blended red pepper] and [black sesame]. In addition to udon, we recommend it as a versatile seasoning for various dishes such as ramen, hot pot, oden, and yakisoba. [Introduction of suridane making experience] Our store was originally the first suridane specialty store in the Fuji Five Lakes area, selling over 20 types of our original suridane. We have prepared a wide variety of spiciness and taste variations, and it has been featured in the media many times, probably because of its curiosity. The suridane base is made with non-spicy red pepper, sesame seeds, bonito flakes, and salt. Even if you add sesame oil to this, it's still delicious as suridane. is also recommended. In addition, we also offer spices such as cumin, coriander, and turmeric, as well as healthy grains such as rice bran, bean curd refuse, and amaranth. You can make your own original suridane, the only one in the world, so it is a highly recommended experience for those who visit Fujiyoshida and Kawaguchiko. Even for small children, it is popular because it feels like an experiment because it is made by mixing various powders. Why don't you make your own original suridane that is perfect as a souvenir for yourself or as a gift for your parents and friends? It takes about 30 minutes. Since it is an indoor facility, there is no problem even if the weather is bad. Please feel free to use it. [This plan is recommended for the following people] ・Those who are interested in suridane ・Those who are interested in making seasonings ・Those who want to enjoy with their parents ・Those looking for hands-on activities ・Those looking for activities in rainy weather direction
