Detchi Yōkan – Fukui Prefecture’s Winter Local Cuisine｜Complete Explanation from History and Origins to How to Make It
Detchi yōkan, beloved by local people as a winter icon of Fukui Prefecture, continues to be cherished by the region’s residents. While mizu yōkan (water-based sweet red bean jelly) is known nationwide as a summer refreshment, in Fukui Prefecture it has a unique food culture of being eaten in kotatsu during snowy, cold winters. This article provides a thorough explanation of the charm of detchi yōkan, covering everything from its history and origins to its preparation methods and ways of eating.
What is Detchi Yōkan (でっちようかん)?
Detchi yōkan is a type of mizu yōkan that is familiar as an everyday taste for common people in Fukui Prefecture. Compared to ordinary kneaded yōkan, it contains approximately 2.5 times more moisture and is characterized by a smooth, slippery texture.
In Fukui Prefecture, there is a custom of eating mizu yōkan while sitting in a kotatsu during winter, and particularly in Ono City it is called “detchi yōkan.” The traditional style is to cut and eat the thick, juicy mizu yōkan that is packed into a box using an included scraper.
Because it contains less red beans and sugar than ordinary yōkan and can be manufactured inexpensively, it has been widely embraced as a taste for common people. It can be said to be a local cuisine representing the food culture unique to the region, making use of Fukui Prefecture’s abundant water resources.
History, Origins, and Related Events
The Name’s Origin and the Apprenticeship Era
The name detchi yōkan traces back to the era of detchi (apprenticeship) during the Taisho and Showa periods. In the detchi apprenticeship system, which is said to have continued for about 200 years from the Edo period, young people from Fukui Prefecture who apprenticed in Kyoto brought back Kyoto’s mizu yōkan when they returned to their hometown of Fukui during New Year’s. This is said to be the origin of the dish.
Detchi refers to young apprentices who worked live-in at merchants’ shops. The yōkan that these young people brought back during their New Year’s homecoming eventually developed uniquely in Fukui and took root in the region as “detchi yōkan.”
Relationship with Fukui Prefecture’s Water Culture
Fukui Prefecture is also known for its abundant water, with tributaries from the sacred mountain “Hakusan” and abundant water sources such as the Kuzuryū and Asuwagawa Rivers. The prefecture also has many springs and groundwater, and the water quality is extremely soft, which has been utilized not only for rice cultivation but also for buckwheat production and brewing high-quality ginjo sake.
Particularly, Ono City is known as the land of famous waters, with “Oshōzu” selected in the list of Japan’s 100 Famous Waters being one such example. Detchi yōkan is a Japanese confection that uses a lot of water, so it is a local cuisine that can only exist with this high-quality water. Even in Ono City, the land of famous waters, many shops manufacture detchi yōkan.
The Establishment of Winter Eating Culture
While mizu yōkan is enjoyed nationwide as a summer refreshment, in Fukui Prefecture it is typically eaten in winter. There are various theories about why this unique eating custom became established, but it is thought that in the era before refrigerators, the cold of winter served as a natural refrigerator, making it easier to preserve mizu yōkan with its high water content.
Additionally, because it was an inexpensive taste for common people, it became established as an everyday snack that families ate together in a warm kotatsu during cold winters. The historical background that yōkan brought back from Kyoto during New Year’s was imprinted on Fukui Prefecture residents’ hearts as a winter taste is also thought to have influenced the formation of this food culture.
Major Transmission Regions
Detchi yōkan is enjoyed throughout Fukui Prefecture, but is particularly vigorously manufactured and consumed in the following regions.
Ono City
Ono City is the region where the name “detchi yōkan” is most established. Blessed with abundant groundwater including Oshōzu selected in Japan’s 100 Famous Waters, the city actively makes detchi yōkan utilizing this high-quality water. The city has several long-established Japanese confectionery shops, each continuing to preserve the traditional taste with their own methods.
Fukui City
In Fukui City, the prefectural capital, many Japanese confectionery shops and food stores sell mizu yōkan when winter arrives. In Fukui City, the term “mizu yōkan” is more commonly used than “detchi yōkan,” but the culture of eating it in a kotatsu during winter is similarly established.
Sakai City, Katsuyama City, and Other Areas
In various regions of Fukui Prefecture including Sakai City and Katsuyama City, winter mizu yōkan is cherished as a local taste. Mizu yōkan made using different methods at each region’s confectionery shops has subtly different flavors and textures, allowing one to enjoy the individuality of each region.
Main Ingredients Used
The main materials for detchi yōkan are as follows.
Red Beans (Azuki)
Red beans, which are the primary raw material of detchi yōkan, are an important ingredient that determines the flavor of the yōkan. Although the amount used is less than in ordinary kneaded yōkan, using high-quality red beans creates a refined taste.
Sugar
Sugar used to add sweetness is also used more sparingly than in ordinary yōkan. This results in a refreshing taste with reduced sweetness, contributing to its appeal as an everyday snack for common people.
Agar
The agar that creates the texture of detchi yōkan is a gelling agent made from seaweed. The texture and firmness of the yōkan change depending on the amount of agar used.
Water
The most important ingredient is water. Because detchi yōkan contains approximately 2.5 times the water content of kneaded yōkan, the quality of water greatly influences the taste. High-quality water from Fukui Prefecture’s abundant water sources supports the deliciousness of detchi yōkan. Detchi yōkan made using famous water from Ono City particularly reflects the goodness of the water in its taste.
Other Ingredients
Depending on the manufacturing shop, a small amount of salt may be added to enhance flavor, or food coloring may be used to adjust the color.
Ingredients (for 10 servings)
The ingredients for making detchi yōkan at home are as follows:
- Red beans: 200g
- Sugar: 150g～200g (adjust to taste)
- Powdered agar: 8g
- Water: 800ml～1000ml
- Salt: a pinch
Compared to ordinary kneaded yōkan, the amount of water is large and the amount of sugar is small. Because of the high water content, a smooth texture is created.
How to Make It
Here is the basic method for making detchi yōkan.
1. Boil the red beans
Wash the red beans thoroughly and boil them in plenty of water until soft. Add water as needed during cooking, and simmer until the red beans can be easily crushed between your fingers. Once cooked, drain the water and pass through a fine sieve to make smooth bean paste.
2. Make the agar liquid
Put water and powdered agar in a pot and mix well while heating. Once it boils, reduce to low heat and simmer for 2-3 minutes to completely dissolve the agar.
3. Mix the ingredients together
Add the bean paste and sugar to the agar liquid and mix well while heating. Once the sugar is completely dissolved, add a pinch of salt to enhance the flavor. Continue mixing until everything is uniform, being careful not to burn it.
4. Pour into molds
Pour the smooth yōkan liquid into molds or containers that have been wet with water. Traditionally it is poured into wooden boxes or shallow containers, but in the home setting, baking pans or plastic containers can also be used.
5. Chill and set
Once it has cooled slightly, refrigerate for 3-4 hours to set. During winter, it will also set if left in a cold place. Once completely set, cut it into pieces using a scraper or knife and eat.
Manufacturing Tips
- By using more water, the smooth texture characteristic of detchi yōkan is created
- The amount of sugar can be adjusted to taste, but using less creates a more common taste
- It is important to thoroughly dissolve the agar
- Using high-quality water significantly improves the flavor
