Bloom the Agar: Start by pouring 2 cups of water into a saucepan and sprinkle in 2 tbsp agar agar powder. Give it a quick stir and let it sit untouched for about 5 minutes.

Boil and Simmer: Place your saucepan on medium heat and bring the agar mixture to a boil. Stir frequently to keep it smooth. Once boiling, lower the heat to simmer and cook for another 2-3 minutes until the agar completely dissolves.

Add the Sweetness and Flavor: Add 2.5 cups granulated sugar to your simmering agar and stir well until completely dissolved, about 1-2 minutes. Remove from heat, then add your chosen flavorings.

Pour and Set: Lightly grease a baking pan or silicone molds with neutral oil, or line a pan with parchment paper. Pour your agar-sugar mixture into the pan or molds and let it cool at room temperature for at least 2 hours.

Cut into Crystal Shapes: Once your jelly mixture is fully set, carefully remove it from the pan. Grab a sharp knife/cookie cutters and cut the jelly into cute crystals, diamonds, cubes—whatever shapes you like!

Air-Dry for the Crunchy Shell: Let your candies air-dry uncovered at room temp for 3-7 days.
