Introduction: Heisenberg's Old Timey Blue Rock Candy

About: Software QA Test Engineer/Technical Writer
What you'll need:

3¾ cups of granulated sugar
1 cup of water
1¼ cups of light corn syrup
1 teaspoon of blue food coloring
1 teaspoon of vanilla extract
Large baking pan
Aluminum foil
Small food storage bag I used 3"x4" (from Micheal's)
Candy thermometer

Put water and corn syrup into sauce pan and heat on medium high and slowly add granulated sugar. Bring to a brisk boil and cover. Let mixture boil for 3 minutes covered.

While this is boiling, line your baking sheet with aluminum foil and spray with non stick cooking spray.

After these 3 minutes were up I tested the temperature and it was somewhere around 230 degrees. Turn the heat up until you can get the mixture to around 300 degrees. Stir in your food coloring and add any flavoring you desire, I used vanilla extract. Remove from the heat and wait for mixture to stop bubbling. Remember stir this stuff often.

As soon as the bubbling stops pour into your prepared baking pan. Put this somewhere out of the way for 2-3 hours hours to cool.

When the mixture is cool and ready to be bagged you will be able to touch it with out it sticking to your finger. Use the back of a metal spoon to break it up and put small amounts on a piece of paper folded in half to funnel it into your bags.

As an added touch I used Gimp to make the labels using the following tutorial (not mine) http://www.youtube.com/watch?v=3CQdjJh-1-A

I think this recipe ended up making somewhere around 45 bags of rock candy.

TROUBLESHOOTING:

Mixture turns brown and has a burnt smell to it. You allowed it to get to hot and or forgot to stir often.

Mixture never sets, is always gooey to the touch. More than likely you did not allow if it to get to the right temperature of 300 degrees.
