Kohakutou is a Japanese candy made from Agar Agar. It is made by pouring flavored jelly into a dish and allowing it to set before cutting or tearing into crystal shapes. The candy develops a crunchy outer crust after a few days but remains delightfully chewy inside.
Place cool water into a medium-sized saucepan
Sprinkle agar agar powder over the water and let it absorb for 5 minutes
Bring the mixture to a simmer and cook for 2-3 minutes stirring constantly with a spatula
Sprinkle in your sugar and continue cooking for another 2-3 minutes
Remove from the heat and add in candy flavoring and citric acid
Pour the mixture into a heatproof, glass dish that has been lightly oiled to prevent sticking
Add a few drops of liquid food coloring on top and swirl with a toothpick. You can blend fully or leave it streaked
Place the container into the fridge for 2-3 hours until set
Remove the set gummy from the container and cut into crystal shapes using a sharp knife
Place the crystal gummies onto a parchment covered cookie sheet and let dry at room temperature for 2-3 days until a hard crust forms on the outside
