  • Richard Hartel, Ph.D., professor of food engineering at the University of Wisconsin-Madison boils a mixture of sugar, water and corn syrup at temperatures over 300 degrees Fahrenheit to produce hard candy. The video demonstrates how the molten liquid candy cools to form what from a technical standpoint actually is a glass. Unlike window glass made of silica, this tasty glass is made of sugar.

    Would be watchable if some "artiste" wannabee hadn't been allowed to inflict their ultra-cuteness on it...

    Wow. Makes me understand a bit more.
    I made candy from isomalt but poured it directly into my mold and the next day they look like they are melted.

    after it has hardened to the glass state, can it be heated again to soften or melt it?

    Is that an induction cook top? If o, I need to cook candy to a hard crack (300 degrees), how would I utilize the induction? It usually takes about an hour to reach 300 degrees so that the water boils out. If the induction unit is cooking faster, how will I know if it has achieved the hard crack needed for hard candy? Thank for your assistance!

    You can also get the color and flavor with Kool Aid powder.

    Thank you Richard. Do you have some website you can recommend where good, but second hand (less expansive) mould machines and probably a small tumbler barrel can be purchased? A lot of people are using silicone moulds lately.... do you think this would avoid having to tumble the candy to get rid of the sharp edges? Also, I have been looking into copper pots... I have read that actually cooking in copper pots that do not have a stainless steel barrier between the cooper and the food is bad... is this true? I must say I agree with other people here... the teeth chomping down on every cut... is quite annoying... Not intended to be a rude comment though!

  • @janiceli551
    @janiceli551 4 года назад +2

    I guess it would be better if the flavoring is added during the boiling process

    • @kameljoe21
      @kameljoe21 2 года назад

      No you add it at the end other wise you will boil out the flavor. You can also stretch this as well to give better color and put air in to the mix which makes for a better candy.

    why did you add acid??? Really wanna know that one.

    • @slipperydick
      @slipperydick 8 лет назад

      It's citric acid, it adds taste to the candy! I've watched several of these candy videos and all have used it, one person said that even if the candy was banana flavoured it wouldn't taste that good unless you added citric acid.

    • @alisonknight5371
      @alisonknight5371 5 лет назад

      Citric acid adds sour taste. The more you use, the more intense the sour flavor

    • @berylvaughan
      @berylvaughan 5 лет назад +1

      acid prevents the formation of crystals. It keeps the candy from tasting gritty--i.e. full of sugar crystals instead of a smooth syrup.

  • @monicalee93
    @monicalee93 11 лет назад

    well citric acid is commonly used in candy making to make it sour, so yea, acid

      @RudeDudeMikeTMTheRudeDudes 6 лет назад

      He obviously did, just not on camera. The mass is very light colored when he adds the coloring and flavoring. Then it cuts to the mass being much darker, implying that he worked the additions into the candy.

    • @lelanddyke8386
      @lelanddyke8386 5 лет назад

      1. Because he doesn't want it to crystallize
      2. Because the all the water boils off before the sugar gets to temp anyway

    @messitup 3 года назад +1

    not scientific at all, didnt explain what the stages are best for, didn't say if it was citric or ascorbic acid, and your candy is way too wet. its gonna be sticky and soft. can already tell by the look of it when it dropped on the sheet tray. a real candy maker rather than some phd would have done a much better job. go watch them.
