Rock candy
What you need:
- 2 ½ cups sugar
- Food coloring
- Flavor oil
- Sauce pan
- Tall narrow glass jar
- Clothes pin
- Short skewers (about 6 cm)
Method:
- Wet the skewer and then coat it with sugar. These will be the seed crystals for growing the bigger sugar crystals. Leave it to dry for a while.
- While the sugar is still drying, place the water in your saucepan and turn it on to medium heat.
- Slowly add in bits of sugar and keep stirring it until all the sugar has dissolved.
- When it starts to boil, take the pan off the heat. The sugar has now turned into a syrup and it is ready when it is thick.
- Add in the food colouring of your choice. If you are using regular food colouring, add 40 drops to make the colour look good in the crystals.
- Pour the syrup into the jar and let it cool in room temperature. It will take an hour or more so keep a close eye on it. If you do not have time to let it cool, and put the skewer in the jar straight away for the sugar to dissolve.
- When the syrup has cooled down, put the skewer into the jar. Clip a clothespin on the end of the skewer and put the sugar covered end into the syrup.
- Let the sugar crystal form over a week.
- Seven days later, pull the skewer from the jar and it should be covered in solid crystals.
Now, you have yummy rock candy as a special treat!
