Kohakutou - Japanese Crystal Candy 🍬
If you’ve seen people buying the Silky Gem brand of these candies…I need you to know how cheap it is to just make them yourself at home. Recipe below!
Ingredients:
½ cup water
1 tsp agar agar powder (3g)
1 cup sugar (215g)
Flavor (e.g. lychee in this video)
Food coloring
1. Dissolve agar agar powder in water and bring to a simmer and stirring til dissolved.
2. Add in sugar, stir until dissolved and then mix in your desired flavouring. Simmer (small bubbles) for about 5 minutes until it thickens into a syrupy texture. Be careful not to over boil (it will spill over and make a mess).
3. Pour into a square or rectangular heat resistant container (or into candy molds) and let cool for 5-10 minutes. Add food coloring into whatever design or color scheme you like.
4. Cool in fridge for 2-3 hours until completely set, then remove from the container and use a knife to cut into whatever shapes you like. Tip: pile up any cuttings to form unique clusters.
5. Place on parchment paper and let dry on the counter for 4-7 days. As it dries the moisture leaves the surface and causes the sugars to crystallize, forming a crispy exterior while keeping a jelly like consistency inside!
Store in airtight jars. This is a fun one to make with friends and family!
