erythritol rock candy on a string experiment
I was asked if erythritol could be use to make the rock candy on a string and although my first thought was to say yes, I decided to do an experiment.

Anyway I thought some of you might find it interesting.

The following is a 2 to 1 solution of erythritol to water.

This was taken about 3 hours after putting the string in the solution.

I do expect that there will be quite alot of cooling effect to this candy when its done in about 7 days.

Interesting! I cannpt wait to see how this experiement turns out!

WOW! The crystallization of this stuff is amazing. I did this with sugar some time ago and it took days to crystalize this much. The following pictures are at 8 hours.

This looks terrific.I suppose you could flavor the solution with flavor oils you use in lollipops to make different flavors.

This proccess also works on wood and the person who asked the question to me wanted to make chocolate mint thin coffee stirrers to use for a party. The mint would also mask the cooling effect. Loranns would seem to be great for this since it is made for candy applications.

At between 10 and 11 hours into this experiment I had to stop the crystal formation. Almost 3 1/2 inches of the bottom of the jar had become solid crystals. If I had let it go much longer I would not have been able to get any of the crystal coated string out because it would have been encased in solid crystals. I drained the erythritol solution and removed as much of the string as I could. I also removed any larger loose crystals. One very surprising discovery I made was when I tried the larger crystal, there was no cooling effect detectable. This candy, as long as it has formed a hard crystal, tastes like a piece of sugar rock candy. The only cooling effect detectable was from the smaller softer crystal that had not completely formed. The crystal on the red lid is about the size of a quarter and tasted like a piece of sugar rock candy. I will show the string when it is completely dried.

This is really neat!

Wow, that is so cool!!! That would be awesome to make a bunch of little ones to stir in coffee or tea, or just eat, hehe. Thanks!

The other day I made a ganache for some LC truffles I was experimenting with for my daughters wedding.

This was the off the cuff recipe I was playing with:

4 oz unsweetened hersheys chocolate
6 T. full fat coconut milk
2 T. sf blackberry syrup
1 splenda quick pack
1/2 cup powdered erythritol

I chopped the chocolate and put into a glass mixing bowl.
Then brought the coconut milk and syrup to a boil and poured over the chocolate and let sit for 5 minutes.
I then mixed in the sweeteners and refrigerated for 15 minutes to set.
I then rolled the granache in 1 inch balls and rolled each ball in misc. coatings such as nuts ad coconut.

They were very good and the testers gave them the :up: .

Anyway to make a long story a bit longer. I was sitting at the table staring at these eythritol crystals after dinner and I all of a sudden remembered I had a bit of the ganache left :doh:

Needless to say these need to be tasted to appreciate the taste sensation.

:kicking: WOW is all I can say!

This fascinates me on so many levels. I HAVE to experiment!!

Oh that rock candy looks GREAT! as does the chocolate

Kisal 03-31-2007 03:05 AM

Kevin, do you think this candy could be made in colors? If so, what type of food coloring do you think might work best, liquid, paste, or gel?

I'm envisioning a pretty bowl full of a mixture of red rock candy and green rock candy for Christmas! :D

I am sure it would work but the only kind I have ever used is the liquid so I have no basis to choose which would work best.

Kisal 03-31-2007 11:04 PM

Thanks, Kevin! My own guess would be in favor of the liquid coloring, since it would be mixed into a liquid solution, as opposed to a frosting or dough. I think I may play around with this a little after I finish my taxes. :D

bumping for bette

I sure wish I had had some of this stuff when my kids were in school!!

Talk about a fun science fair project! We ended up growing cultures of swabs taken off doorknobs in various public bathrooms. Now that was scary!

Thanks for sharing.

Did you ever post the pic of the dried string Kevin? I am going to try this.

Kevinpa 07-15-2007 07:51 PM

No, by the time I tried to get it out of the jar, the crystals were so large I could not get it out in 1 piece.

HI, I have one question about this rock candy made from Erythritol? Did you heat/boil the original erythritol/water mixture? If so to about what temp? Thank you so much. I'm trying to make a HOT cinnamon sugar free hard candy using Erythritol and no having much luck finding recipes. Any help you could give me would be very much appreciated. Elaine
