{"id":169504,"title":"Mizu y\u014dkan \u2013 Japanese red bean jelly","modified":"2026-08-29T15:53:45+02:00","plain":"A light y\u014dkan made with agar-agar and red bean paste, delicately sweetened and best served thoroughly chilled once fully set in the refrigerator.\n\n\n\nThe air is heavy, the appetite is lagging, and yet a slice of mizu y\u014dkan straight from the refrigerator disappears in three bites. The block quivers on the spoon, breaks with a clean snap, then melts instantly on the tongue, leaving behind the rounded flavor of adzuki and the freshness of clear water. \n\n\n\nThere is almost nothing in it : red beans, kanten, water, a pinch of salt. It seems almost too restrained to leave an impression, until you reach for a second slice.\n\n\n\nA different side of red beans, this time served hot : zenzai\n\n\n\nWhat is mizu y\u014dkan ?\n\n\n\nMizu y\u014dkan literally means \u201cwater y\u014dkan.\u201d It is a wagashi, one of the Japanese confections often served with green tea. The name says it all : it contains far more water than neri-y\u014dkan, the dense, sweeter version designed to keep for a long time. A good mizu y\u014dkan breaks cleanly, without elasticity, melts quickly in the mouth, and keeps an even color from top to bottom.\n\n\n\nThe word y\u014dkan itself has distant origins. Its characters originally referred to a Chinese mutton soup that set as it cooled, brought to Japan by Zen monks. Vegetarian Buddhism did the rest : the meat gave way to adzuki beans, flour, and starch.\n\n\n\nSame adzuki paste, a completely different form : dorayaki\n\n\n\nFrom mutton stew to adzuki jelly\n\n\n\nIn the kitchens of medieval temples, sh\u014djin ry\u014dri forbade animal flesh. Cooks therefore reworked the imported preparation into a plant-based version : adzuki for color and depth, flour and starch for structure. The result was no longer a soup, but a steamed sweet.\n\n\n\nThe Edo period changed everything. Kanten, perfected in the 17th century, made it possible to turn sweetened bean mixtures into clean-cut jellies that were easy to slice, instead of heavy blocks. By the early 19th century, the journal of Kaneko Tsurumura, from the Kaga domain, already mentioned mizu y\u014dkan as a category in its own right : lighter, more watery, more delicate.\n\n\n\nThe paradox of seasonality remains. Department stores sell it as a July and August treat, tailor-made for och\u016bgen gifts, but in Fukui and Nikk\u014d it belongs to winter: before refrigeration, only cold rooms and the brisk mountain air could protect a sweet this hydrated. Even the vocabulary changes from region to region. \n\n\n\nIn Fukui and parts of Kansai, \u201cdecchi-y\u014dkan\u201d refers to a particularly watery mizu y\u014dkan, whereas in Shiga the same word refers to a steamed confection made with flour and beans, wrapped in bamboo leaves.\n\n\n\nAnother sweet served ice-cold : mochi ice cream\n\n\n\nThe main ingredients in mizu y\u014dkan\n\n\n\n\n\n\n\nKoshian gives mizu y\u014dkan its structure, muted reddish-brown hue, and bean flavor. The skins are removed and the paste is strained, which is why the gel is silky rather than grainy. Water, meanwhile, is the ingredient that gives the dessert its name : it makes it light and refreshing, but also highly perishable and far trickier to get right.\n\n\n\nKanten is the gelling agent, derived from tengusa and other red algae. It activates at a boil and sets between 30 and 40 \u00b0C, producing a firm, brittle gel that remains stable at room temperature. \n\n\n\nGelatin does not do the same job: because it is animal-based, it melts at body temperature and adds elasticity rather than that clean snap. Some products sold as agar-agar, when formulated differently from pure kanten, also produce a softer, wobblier texture.\n\n\n\nSugar is generally white, but Fukui versions often use kokut\u014d, which is darker and carries notes of molasses. A pinch of salt sharpens the sweetness, brings out the earthy side of adzuki, and avoids a flat finish. Even the water matters : soft, low-mineral water, like that found in the mountains of Nikk\u014d, gives a more delicate set.\n\n\n\nServe with tea, just like mitarashi dango\n\n\n\nSigns of authenticity and pitfalls to avoid\n\n\n\nEverything shows in the slice: smooth and uniform, with no pale layer on the surface and no dense band at the bottom. A two-layer block signals bunri, the separation that occurs when the bean paste sinks before the gel sets. \n\n\n\nThe fix comes down to one step: let the mixture cool while stirring until it thickens at around 40 \u00b0C, so the paste stays evenly distributed. And because the dessert is highly hydrated, it should be kept in the refrigerator and eaten within three to five days.\n\n\n\n\n\n\tMizu y\u014dkan - Japanese sweet red bean jelly\n\t\t\n\t\t\t\n\t\n\t\t\t\n\t\n\t\t450 g water2 g agar-agar powder15 g brown sugar (preferably kokut\u014d)250 g koshian (smooth red bean paste)0.5 g salt\t\n\t\n\t\tCooking the jelly baseCombine the water, agar-agar, and brown sugar in a saucepan.Heat, stirring, until fully dissolved.Bring to a boil and boil for at least 1 minute (this step is essential for the jelly to set).Add the salt.Press the koshian through a sieve, then stir it into the mixture until smooth, as you would with miso.Cook, stirring, for about 15 minutes, until slightly thickened.Cooling, setting, and servingLet cool for about 20 minutes, stirring to release the residual heat (this prevents the mixture from separating into two layers).Pour into a rectangular dish.Refrigerate until completely set.Cut into portions and serve well chilled.\t\n\t\n\t\tImportant: Stirring the mixture as it cools is essential; otherwise, the bean paste and agar jelly will separate into two layers.\nSugar: About 15 g gives a sweetness reminiscent of traditional confectionery, while 30 g produces a firmer, more reliable set that is easier for beginners.\nVariations: Add chestnuts, or make a version with salted cherry blossoms by pouring a second cooled jelly (200 g water, 2 g agar-agar, 20 g sugar) studded with desalted cherry blossoms over the fully set jelly.\n\t\n\t\n\t\tDessertJaponaise","_links":{"self":[{"href":"https:\/\/marcwiner.com\/en\/wp-json\/wp\/v2\/posts\/169504","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/marcwiner.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/marcwiner.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/marcwiner.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/marcwiner.com\/en\/wp-json\/wp\/v2\/comments?post=169504"}],"version-history":[{"count":0,"href":"https:\/\/marcwiner.com\/en\/wp-json\/wp\/v2\/posts\/169504\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/marcwiner.com\/en\/wp-json\/wp\/v2\/media\/169449"}],"wp:attachment":[{"href":"https:\/\/marcwiner.com\/en\/wp-json\/wp\/v2\/media?parent=169504"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/marcwiner.com\/en\/wp-json\/wp\/v2\/categories?post=169504"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/marcwiner.com\/en\/wp-json\/wp\/v2\/tags?post=169504"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
