tutorial: how to make edible Agates

Kohakutou edible jelly crystals have been one of the most popular recipes on my Instagram! This doesn’t surprise me at all because they’re translucent and striking when they’re first done. When these Asian treats dry they become crunchy on the outside and stay soft gummy on the inside. And of course what’s most important – these little guys are so delicious because they’re mild, sweet and great textures.

For fun, let’s make some edible agate shaped crystals together! For this project you don't have to purchase any molds - we'll make them together with foil! SUPER easy. And, I know these look like coasters - but please don't use them that way (:.

See my video for a demonstration of how I form agate with edible gummy crystals - so easy and fun!

Step 6 – Add color and/ or edible glitter to your crystal mixture. I don’t add the color in advance because it dries and sticks to the bottom of the container. The mixture cools really quickly so I just work very quickly.
