Suiton

Suiton predates udon and soba — the word 'suiton' (水団) appears in Muromachi-period records, though the modern hand-torn form only took shape in the late Edo period, when wheat was a poor-soil crop in Tohoku. The dish became culturally iconic during the 1940s wartime and postwar food shortages, when rice was rationed and flour was the only staple available. Generations of Tohoku elders associate suiton with hunger; the dish is now eaten more from memory than necessity.

Flour-and-water dumpling soup recorded since the Muromachi 14th century, when wheat fed the poor-soil prefectures. Became a Tohoku ration-memory dish in the 1940s — most elders still eat it tasting of hunger.

Hand-torn flour-dough lumps simmered in a dashi-soy or miso broth with whatever's at hand — root vegetables (daikon, carrot, burdock), pork or chicken, sometimes mushrooms. The dumplings are uneven, irregular, soft outside with a denser core; they thicken the broth as they cook. Cheap food, peasant food, postwar-rationing food. Still eaten in winter Tohoku homes when there's not much in the fridge.

The dough has no eggs, no leavening — flour, water, salt, sometimes a splash of oil. Tearing rather than rolling and cutting matters: the rough surfaces grab broth and starch leaches out at the edges, lightly thickening the soup. Drop the pieces into already-simmering broth (not cold, or they dissolve). Resting the dough 10-15 minutes before tearing relaxes the gluten so the cooked dumplings aren't rubbery.
