Make Rock Candy

Rock candy is an old-fashioned candy that is just as much fun to make as it is to eat.

You’ll need

Clean glass jar (a mason jar works well)

Cotton string (butcher’s twine or crochet thread)

Pencil or skewer

4 cups granulated sugar

2 cups water

Food coloring (optional)

½-1 tsp flavoring extract or oil (optional)


1. Cut a length of cotton thread a few inches longer than the height of the jar, and tape it to the pencil. 

2. Wet the thread and roll it in granulated sugar.

3. Place the water in a pan and bring it to a boil.

4. Add the sugar one cup at a time, stirring after each addition.  Add the enxt cup only after the prior one has dissolved completely.

5.  One all the sugar is added and disolved, remove the pan from the eat and add flavor extract and food coloring, if desired.

6. Allow the sugar syrup to cool for about 10 minutes, then poor

7. Place the pencil across the lip of the jar and wind it until the thread is hanging about 1 inch from the bottom of the jar.  If necessary, attach a paper clip or other small item to the end of the thread to weight it and ensure it hangs straight.

8. Store the jar in a cool place where it can sit undisturbed.  Cover loosely with plastic wrap or paper towel.

9.  Allow the rock candy to grow until it is the size you want (note:  this may take a few days.  Once it is reached the size you want, remove it and allow it to dry a few minutes before eating.  Or, wrap it in plastic and save it for later. 


the reward of patience

Trouble shooting:  You should see sugar crystals forming within 4 hours.  If you don’t see any in growth in 24 hours, try re-boil the syrup and add an extra cup of sugar to it, then try again.

Warning: This activity involves using the stove.  While people with moderate and even severe stages of the disease may be able to stir the mixture, if necessary for your individual and their stage of the disease, please provide the appropriate supervision whenever a heat source is in use.
