Reheating Hard Candy

Does reheating hard candy work?

I tried to make hard candy, but I stopped heating too soon and it didn't reach hard crack. Can I reheat my already-cooled candy until it reaches hard crack, or am I stuck with this soft candy?

Thank you,

Hi Andrew,

The question of whether or not you can reheat your hard candy mixture and try again is a matter for debate and opinion.

For example, some visitors have said that they've had success by reheating their peanut brittle mixture both in the microwave and on the stove top in order to get it to set properly.

The common denominator in all situations is that you have to be extremely careful and watchful to make sure that the candy mixture doesn't burn.

You definitely would have had more luck reheating the candy while it was still warm, but you may still be able to salvage it even though your candy mixture has cooled.

I've got a tremendous sweet tooth, but I'm NOT a science buff. The truth of the matter is that candy making definitely has a lot of science behind it. The way the sugar crystals melt and re-form, etc., is part of the equation and different variables lead to success or failure in candy making.

I personally haven't tried cooking hard candy back down again in an effort to boil it to a higher temperature, so I'm interested in hearing your results. Just go slow and let us know how it turns out for you.

Theoretically, melting hard candy successfully should work. One of the hard candy Christmas recipes calls for melting hard candies in the oven to create a "stained glass" effect. It's a lovely concept.

I'm definitely looking forward to hearing back from you on whether or not reheating hard candy mixture to the required temperature is going to fix your soft candy. Do let us know!

Reheating hard candy NEW
by: Maggie

I had extra in the pot and not enough lollipop molds which, of course, solidified while they were cooling. So I just warmed it up to liquid (not to 300 deg) regreased the molds, poured in the melted candy, and it set fine.

It worked! NEW
by: Sarah

Soooo glad I found this question. My BF and I decided to try making the hard tack candy his mom made as a kid. We were successful with our single batch, but the two double batches we made next never fully hardened. Some reading suggested that for double batches you actually have to increase the temp (300-310) beyond that for a single batch (275-280). We tried the advice here. We put it back into a pot with about a 1/4 cup of water, let it melt on a low temp, and then brought it back to a boil. This time we used both the thermometer and the water test just to be sure. We were able to savage both batches!!

Hard ball candy
by: Carla

Good Afternoon,

I am making candy apples for my sons bday party and I was wondering if after taking my sugar mix to 310 if there is way to maintain it in a liquid state for a longer period of time? I have a lot of apples to dip. lol

Thank you in advance for your help.

Reheating hard tack candy that's under done
by: Patricia

I've made this candy for 40 yrs and totally messed up this time.
Heated to 300 because that's what the new candy instructions say,guess what,sticky results. I put it in a saucepan added some water,kept stirring until it was all liquid and cooked it up to 310 degrees added a teaspoon more flavoring poured it out as usual and it was perfect. So thankful for this sight.

Reheating hard candy
by: JoAnn Aud

Well I just tried it. It was toffee and what I did was I didn't wait till I got a hard it didn't reach the temperature I wanted to cuz a candy thermometer broke so I pulled it off guessing and guessed wrong. as it was soft and it was cooling down I put it in a glass bowl that was microwavable and I put it on for 3 minutes. The butter separated but not all of it it's not a nice pretty shape but I'll be done it worked yay me yay microwaves..

It works!
by: Pandora

For some reason my almond roca didn't go to hard crack. I was reluctant to try reheating it again to hard crack, but what did I have to lose? I reheated it with 1/4 cup water and kept my eye on it. I really don't think my thermometer helped. Neither did dropping a little bit into cold water. I just kind of went by time and color. It turned out perfect. Good thing because it's not inexpensive to make. I'm a happy girl.

reheating hard candy mixture
by: Mrs V

I was making alcohol lollipops for a bridal party and i only had for candy molds so i had to wait for those to harden before i could use the rest of the candy mixture. which had already begin hardening in the pan. basically you can reheat your candy mixture by just adding some water a tip i got from one of the answers on here and it worked you just have to bring it back to a boil and start that process all over again until it reaches the crack hard stage again. so yes it can be done

Reheating Hard Candy
by: Anonymous

I am currently making hard candy suckers for Easter. I also didn't have enough molds for the candy! While I was letting the first batch of suckers set up I tried to reheat the candy after it had already started to set. I added about 1/4 cup of water. I brought it to a boil and stirred frequently until it was all liquid once again. I am boiling it to 300 and then I am gonna take it off the heat and proceed with another batch of suckers! It can be done!

Reheat Hard Candy
by: Angie

Hi Tam,

I don't think you'll have much luck reheating hard candy mix if it has already set, but you could give it a try. You'll probably need to add a bit of water and then cook it longer to reach the 300 degree F. hard crack stage, giving the water a chance to evaporate.

I'm not 100% sure that will work without burning the mix, but I'll be interested in hearing if it does!

If the situation occurs again that you have more mix than molds, you can use the remaining candy to make "hard tack" candy right away rather than worry about what to do with the excess hard candy mix after the fact.

Just pour the remaining hot mixture onto a buttered/oiled cookie sheet. Butter your hands and start cutting the warm candy into small pieces and roll between your palms to keep from having too many sharp edges.

You can then toss the candy pieces in powdered sugar and store in an airtight jar. This makes nice bite-sized pieces of candy and you don't have to waste a drop of your mix.

Hope that helps!
