OK, so I'm trying to make fudge. The recipe which I'm following doesn't give all that much in the way of directions. So I'd like clarification of a few points, so I know what I'm aiming for.

  • Am I right in thinking that the objective is to heat the mixture as slowly as possible, and then cool it down again as slowly as possible?

  • Some sources seem to claim that you want to stir the mixture until everything disolves, and then stop stiring it and just let it boil. Is that correct?

  • The plan appears to be to heat the stuff until it hits the magic temperature of 115°C or 116°C (depending who you ask), and then stop heating it and let it cool down again. (?)

  • How crucial is it that it's exactly 116°C? I mean, obviously if it was way hotter or colder, that would be bad. But what kind of tolerance are we looking at? Is 2° either way going to matter, for example?

  • The recipe talks about letting the mixture cool for a while, and then stiring it "until the gloss finish disappears". Is it crucial exactly when you do this? Does it have to cool to a specific temperature or something? (I've seen recipies that seem to suggest constant stiring all the way through, and others that say to only stir once cool...)

  • In the past, I've bought fudge and left it unwrapped, and it dries out and becomes inedible. How do you stop this happening while you're waiting for your freshly cooked fudge to cool down? Should it not be a problem?

  • Flavourings should be added at the end. (?) Should it be while the mixture is still hot, or once it cools down a little? (Currently I'm using vanilla essence, but obviously I'd like to try some other things - if I ever get the fudge itself to work...)

I guess that's quite a lot of points for just one question, but I think it shouldn't be too hard to answer them all in a fairly short answer.

    Your questions seem to be all related to general candy-making concepts, for example - the temperature relates to the mixture reaching the "soft ball stage" which would be good for you to understand before beginning your candy-making. Here's a link that should answer your basic questions. Maybe you can bring specific questions after you've done the research and tried again, using your new-found knowledge.

I like Kristina's suggestion that you research some of the basics of candy making. I'll answer those questions only briefly.

Generic Candy Questions

  • You don't need to heat particularly slowly
    This is not like an egg custard where the speed of heating will affect the curdling temperature. You're just trying to get water out. Just don't heat it so fast that you burn the bottom or overshoot the target temp.
  • Temperature range
    The different candy stages have about a 10F range. 2-5 degrees isn't going to make much of a difference but 7-12 will start to.
  • Adding volatile flavorings to candy
    Many flavorings are lost to heat. Such flavorings are added at the end because if they boiled the entire time they would be gone.

Fudgy questions

  • Stirring
    Stirring isn't required. The syrup won't burn unless you have the heat too high and are using a very cheap pot. Additionally, the syrup absolutely should not be stirred in the final moments of boiling because a sugar crystal might fall in that doesn't get dissolved. During cooling stirring would destroy the fudge because it would all crystallize.
  • Drying out
    This is not a problem. The fudge will not dry out in the time it takes to cool.
  • Losing the gloss
    As I wrote in the other answer, the syrup is concentrated and then cooled to a super saturated state and not allowed to crystallize. When it has cooled sufficiently it is mixed like crazy to form your crystals all at once. When this happens the shiny, glossy syrup suddenly fills with crystals and becomes thick and loses the gloss.

    It is important that the syrup be cooled enough that it is ready to crystallize at the drop of a hat. Again- if you stir it early, as it cools, you will end up with rock candy (more or less). I just leave my candy thermometer clipped on until the target temperature is reached. Make sure the thermometer is clean- one stray sugar crystal can ruin the batch.

    Great summary. I would always suggest med-low, med temp for beginners, as it only take a small distraction to burn a load of sugar. Especially with tests, as you tend to use small single batch recipies

  • "End up with rock candy" appears to be what happened to my most recent batch, sadly. (Although it still tastes good.) You don't say what the "target temperature" for cooling is... Commented Oct 1, 2012 at 8:47

    @MathematicalOrchid- Cool to 110F. Commented Oct 2, 2012 at 2:01

It is my opinion and experience that you never stop stirring before or after boil, and yes I do bring it to a boil slow, on med heat. Then I stir boil for 4 minutes. Fight the urge to go to high heat. It'll be worth it. Also a small invest in candy thermometer will help you remove it from burner at the perfect time, to add the chocolate, vanilla and marshmallow cream. After the stir ins, it goes into my buttered/greased pan to cool and firm beautifully.


With proper fudge making even the humidity of the day can affect crystallisation and setting. It is a science and an art.

On the other hand, there are plenty of very nice 'fudgy' candy making recipes that are much easier such as the 'Carnation Condensed milk' recipe that relies on the solid chocolate bars for setting. Icing sugar is added in the end to give it the crystal texture people associate with fudge. I find this fudge very good to keep and cut, though a little bit too chocolatey if there is such a thing!

Any 'fudge' that has lots of solid chocolate added is actually more of a chocolate recipe to soften that chocolate, by adding butter or condensed milk to make it like fudge.

Also look up Marshmallow Fudge. Some people like it as it is completely smooth and silky, but others find it a bit sickly or chemically tasting. That might depend on the brand of marshmallow used.

  • Clarifying 'Fudge making' vs Candy-- Giving people options to try different things if actual fudge making is too technical. At least I did not tell off the poor person asking for not knowing enough.
