Enchanting our palates for centuries, konnyaku made its debut in Japan as a medicinal food in the 6th century. This gelatinous delight is derived from the starchy konjac plant, a root vegetable native to Asia. The jelly presents itself in an array of colours, from dark greyish with the addition of hijiki seaweed to a pristine white without additives, each hue offering a unique culinary experience.

The konjac plant, also known as elephant foot yam or Devil’s tongue, is the primary source of Konnyaku. Introduced to Japan from China, the konjac plant has since been selectively bred, resulting in the development of five unique species such as haruna-kuro (はるなくろ) and akagi-odama (赤城大玉・あかぎおおだま).
This plant, cultivated by planting seed tubers or one-year-old tubers in spring, grows over the summer and is harvested in late autumn, a cycle that ensures a constant supply for the production of konjac jelly.
Behind the Scenes: The Art of Making Konnyaku
The production of konnyaku involves the following steps:
From Root Vegetable to Powder
The humble konjac plant is carefully cultivated and then transformed into a fine powder, setting the stage for konnyaku creation. Picture the konjac root, dried and ground, its essence captured in a powdery form, ready to be reborn as konnyaku.
Transforming Powder into Jelly
Imagine the konjac powder as a butterfly waiting to emerge from its cocoon! This powder is mixed with water and natural gelling agents, embarking on a transformation. As it's stirred and heated, a miraculous change occurs—the mixture evolves into a gelatinous form, much like a caterpillar metamorphosing into a butterfly.
The artistry in this process lies in balancing the mixture's temperature, pH levels, and the precise addition of coagulants. This careful orchestration ensures that the gelling process is just right, leading to the perfect texture of konnyaku.

Crafting Culinary Masterpieces
Once the konnyaku mixture has gelled, it's poured into moulds to solidify. This jelly can be infused with various flavours or colours, adapting to the whims of culinary innovation. The result is a delightful array of konnyaku varieties, each offering a unique taste and textural experience.
