    What is Suiton?

    Suiton is a dish originating from Gunma prefecture, created by turning flour dough into small pieces through methods like shredding, rolling, or scooping with a spoon, followed by boiling in soup. To make Suiton, locals added water to flour, creating a dumpling-sized dough that is then boiled in soup. Locals made this type of dumpling with gluten-containing grains or nuts ground into powder, mixed with water, and dropped into hot water or soup. How it’s served varies based on the cook’s effort, ingenuity, or local customs. There are different variations, including simple ones resembling dango made by kneading with water and dropping into hot water, and zoni-style ones prepared with miso soup or clear soup.

    Suiton History

    The word “Suiton” has theories suggesting it originates from “taking and throwing” flour in water or “dad stirring the pot.” Also known by other names like “Tsumerikko,” “Otsuyu Dango,” and “Nejikko,” each reflecting the unique culture of different regions. The term “suidan” first appeared around the Nanbokucho period, but its exact culinary meaning remains unclear. The preparation method for Suiton evolved, and the hand-made wheat flour format we know today emerged in the late Edo period. During the Edo period to the pre-war era, there were specialized stalls and restaurants for Suiton, making it a popular taste among the common people. In the mid-Taisho era, the number of Suitonya decreased, but after the Great Kanto Earthquake, Suitonya emerged in the burnt-out areas, reflecting the challenging food situation at the time.

    In Gunma, a region known for practicing double crops of rice and wheat, the production of wheat flour has a long history, leading to the popularity of various flour-based dishes like okirikomi and Manju as local cuisine. One such dish is “Suiton,” made by dissolving flour and water. Although Suiton is made throughout Gunma, the ingredients and names may vary by region. For instance, Ota City’s version often uses rice flour, while in Fujioka City, it is called “Tochanagejiru” despite being made with wheat flour.

    The term “Suiton” locals used across Japan, but its name changes depending on the region, such as “Hittsumi,” “Hatto,” “Tsumeri,” “Tottenage,” “Tochanage,” “Odansu,” “Hinnobe,” and “Dagojiru.” Each region has unique ingredients, soup stock, and cooking methods, making these suiton-like dishes distinct local specialties. Even within the same region, households may have different cooking methods and dish names. In general, suiton dishes can be broadly categorized into soy sauce or miso flavors, and variations in flavor can also arise from different water amounts or preparation techniques, such as using a spoon, tearing by hand, shaping manually, or otherwise.
