Rock Candy

22 Aug
  • 2 cups water
  • 1 cup white corn syrup
  • 3 1/2 cups sugar
  • 1/4 tsp cream of tartar
  • 1/4 tsp vanilla extract
  • 3 drops of blue gel food coloring

I boiled the mixture and then continued stirring it on the heat until it reached 300 degrees F (used a candy thermometer to measure the temp). At that point, I poured it into a tray to cool. It hardened up in about an hour and then I smashed it to pieces. via reddit

      I don’t think I would pass them out in the little baggies… it does look suspicious that way! Yikes!

    It looks like drugs because it’s basically a replica of how they make Blue Sky meth in Breaking Bad (minus the actual meth, of course).

    Could I make this into cinnamon candy?

      I would imagine you could get a cinnamon flavor from the candy making and baking aisle in a craft store walmart etc. I havent made these before but im sure it would work fine.

    When you say 3 1/2 cups of sugar, what kind of sugar do you mean?

    • Liz

    Some of you people are absurd! Drugs?!?! Really?? So I am sure kids will think that right away! If you are doing a Frozen theme party I do not see how anyone would think that about this candy! I Hate how people ruin such wonderful ideas! (smh) Shame on you!

      If you look at the source, you’ll see this was originally made for a breaking bad party and is supposed to look like the blue meth on the show.

      Dear Liz,
      Hi. You shouldn’t berate people online and be so harsh unless you know why. There was a very popular tv show that almost everyone in the world knows about. That show is called ‘Breaking Bad’, which aired on AMC from 2008-2013. Please feel free to search online and/or watch it(it’s captivating). In the show, the 2 main characters make Meth(drug) it is blue and glasslike and they would put them in those little plastic baggies to sell to the drug addicts. You became very angry and defensive towards people on here. :/ They weren’t making up any false statements. Anyone who has watched the show KNOWS that this original post/recipe was actually a tongue in cheek recipe actually referring to the TV show ‘Breaking Bad’. Hope this made sense, I’m under the weather.
      Take care Liz! :)

    Well Liz, I suppose if the post didn’t refer to this candy as looking like meth and wasn’t put in little baggies. People wouldn’t be saying anything about it. Really. I guess I could see how this would be pretty cool for a Breaking bad party but I sure wouldn’t be giving this to kids. Just me, maybe.

    I have Karo corn syrup? Will that work..

  14. Jenn

    October 10, 2014 at 6:37 pm

    Did you put powdered sugar on the candy after you broke it up to keep it from sticking together?

    • haha

      April 20, 2015 at 1:36 pm

      Probably because this was originally made for the breaking bad finale. Check out the source! This is supposed to look like the blue meth from the show.

    • Don't be so clueless :)

      May 5, 2015 at 9:16 pm

      Either you are a troll or just clueless. Please read above, this IS a reference to the tv show ‘Breaking Bad’. The ORIGINAL POST(not frozen party) INTENDED on making this as a DRUG reference to the BLUE METH that was made and sold to drug addicts on THE TV SHOW. smh
      Watch popular tv shows much? lol I can imagine the look of horror on those parents faces who watched Breaking Bad when they take their kids to a party and see this Blue Drug candy! LMAO
      Stop arguing with people and RESEARCH before you make an attempt to be passive agressive.
      ANY parent making this for a childs party will be laughed at and frowned upon. Lol

    Do I need to use a non-stick spray on the cookie sheet before pouring the sugar???

    • Shannon Saluzzi

      January 9, 2015 at 6:40 pm

      Parchment paper or a silicon mat would work or other wise I would spray lightly. i have also heard of people using kool-aid to flavor this

    January 10, 2015 at 11:13 am

    Can this be made in advance & stored for about a week? If so how would you store it? Should I wait to break until ready to use? If broken will it stick together?

    January 13, 2015 at 12:46 pm

    Hahaha this is FOR SURE from Breaking Bad

    Wow, really? I can’t imagine why anyone would take a KIDS party idea and make a drug reference unless they were immature or a drug head themselves. Grow up people, your opinions reflect your IQ. Lol

    • haha

      April 20, 2015 at 1:35 pm

      Lol check the source! Its originally from the breaking bad sub reddit for the finale! Use it for a kid’s party, but this was definitely originally meant to look like drugs.

    Tried this but went from blue to green-burnt in like seconds when hit 300 degrees. Sort of dangerous too, as it becomes like shards of glass. Oh well, looked interesting.

      I have made sugar glass a few times and have learned that you should not put any coloring in until the mixture is 280 degrees, then make sure to take it off the heat as soon as it hits 300. When I use isomalt it says to put the whole pot in a bit of water to stop the cooking. It is kind of scary as you can imagine putting something that hot into water bath & I wouldn’t do it with a good pot but my sugar glass turned out perfect every time.

      From experience, my best suggestions is to make sure it reaches 300 degrees or “hard crack” stage. Also do not put it in the refrigerator, let it harden at a cool room temperature.

    February 27, 2015 at 11:38 am

    My mixture stood over night and didn’t harden. What am I supposed to do?

    I have tried this recipe, it didn’t work out. I figure out later, need to add more tartaric acid than advised.

    I used candy floss sugar (cotton candy sugar). It is already colored and flavored. No fuss no muss. Turned out great.
    For everyone freaking about it looking like meth. Get real people. Just because the recipe calls for “blue”, doesn’t mean you have to make it blue.
