These things are SO COOL to make. But they do take a lot of time to let the rock candy create itself. And it’s something best done without magic as it works better slowly then just making the liquid evaporate quickly.
It has two parts so I’ll list the stuff for each part separately in the order you have to make them.
This makes one half a rock candy geode that’s about the size of your palm. To make more than one of these adjust the recipe accordingly. You can also experiment with larger sizes of them and more sugar solution.
If you want to make the kind you actually crack open, you gotta make a really thick chocolate layer in a large hollow chocolate mold. The shell for these has to be Like a half inch thick or more shell. This takes some doing, as if you make it with thinner sides, the warm sugar solution eats through the chocolate and just makes a mess. Which is why you do the rock candy first in the smaller types! Once you have a good thick shell you fill it with the sugar syrup and turn it every so often while it creates the rock candy inside it. Then get a hammer and crack it open!
You can also use molds and line them with the tin foil for the first step to make them in shapes like eggs or whatever. Long as its for a hollow chocolate.
For the inside You will need!
- 3 cups sugar
- 1 cup water
- few drops of food coloring
- few drops flavouring
- Thick Tinfoil
- Measuring cup
- Tea towl
- Using aluminium foil, make a bowl in a rock shape. Place this inside a bowl and crumple up more tinfoil along the sides to support the rock shape. Try to make sure your rock shape has no folds and is as smooth as you can get it or sugar may get into the folds and you’ll have to pick that out later.
- Heat the sugar and water in the saucepan and stir until completely dissolved. If you want to add food colouring or a flavor you add it here too.
- Remove from the heat.
- Pour the hot sugar solution into the rock shape in the bowl, completely wrap the top in another sheet of foil and over in a tea towel.
- Leave for 48 hours for crystals to form. Tip off excess sugar solution, peel off any foil and leave upside down to drain for half day until its all dry.
For the outside You will need!
- 1 cup white chocolate melts or candy melts
- 1 cup milk chocolate melts or candy melts
- OPTIONAL, other colors of candy melts
- Measuring cup
- Flip the rock candy inside upside down onto a plate so the shiny smooth side is up.
- Melt the white chocolate or candy melts in your prefered method and pour over the back of the candy shell, let it harden.
- Repeat with the milk chocolate or a colored layer, you can keep adding layers like this till you get as thick a shell as you want with as many colors as you want.
- Flip it so the candy side is up and trim off any excess chocolate if you want smooth edges. Or leave it wobbly messy if you like.
