Kohakutou (Edible Japanese Crystals)
While it may appear to be crystals or gems due to its colorful and transparent appearance, Kohakutou is a traditional Japanese candy that has recently regained popularity in Japan, thanks to its Instagram-worthy qualities. Experience the unique texture of its crispy exterior and jelly-like interior, referred to as 'edible crystals.'
Ingredients
- 2 tsp (0.15oz./4g) agar-agar powder
- 10.6 oz. (300g) granulated sugar (Other types of sugar can also be used, but granulated sugar will give you a more transparent finish due to its high purity.)
- ⅚ cup (200ml) water
- liquid food coloring, flavored syrups, or liqueurs
Instructions
- Mix water and agar-agar powder in a pot and bring it to a boil. Once it comes to a boil, reduce the heat to low and simmer for about 3 minutes to fully dissolve the agar-agar.
- Add sugar to the pot and continue simmering for 5-10 minutes, stirring with a spatula until the mixture thickens. The consistency should be thick enough so that when you lift the spatula, the liquid mixture forms a string.
- Wet the inside of a glass or metal container, and pour the liquid mixture into it. If there is any white foam or bubbles on the surface, remove them with a spoon before adding liquid food coloring (or flavored syrups or liqueurs). Then, let it chill in the glass or metal pan in the refrigerator for an hour.Note: To create a marbled pattern, wait for about 10 minutes until the mixture cools before gently mixing it with a skewer or spoon.
- Cut the solidified mixture into your desired shapes using your hands, a knife, or molds, and arrange the pieces on parchment paper, ensuring they do not overlap. Allow them to dry in a well-ventilated room until the surface firms up and develops a frosted glass-like appearance.
- Once the surface of the pieces has firmed, flip them over and continue the drying process until the other side also firms up. The total drying period is approximately 5 to 7 days.
Notes
- You can store it at room temperature for up to 2 weeks. Avoid refrigeration, as condensation may cause mold growth.
