When my son was small and we were just beginning our homeschool journey, my good friend, Tanya, loaned me her Sonlight curriculum for grade 1. Although I chose not to use it, I did read most of the books to my little boy. I have wonderful memories of sitting under the big maple tree in our backyard reading one of our favorites, “Little Pear,” by Eleanor Frances Lattimore. In this enchanting book, the main character’s favorite treat to buy is a tang hulur. My child liked this book so much that we borrowed the others in the series from the library. Our favorite part that has stuck with us all these years (he is 12 now, but still likes to be read to!) is the fascinating idea of a tang hulur. We have our own idea of what they look like, and when we see a resemblance of our conception, whether it be in a store or picture, we always exclaim, “Look! It’s a tang hulur!”
In this blog post, I share with you the day we made tang hulurs, better known as rock candy. This is a fun activity to go along with a science lesson or unit on rocks. We actually made the rock candy with our small Pathfinder group as part of the Rocks and Minerals honor. We had attended a gem and fossil show the week before, a first for all of us. A day or two later, I received an email to sign up for a free online science class to learn about rocks, including experiments to do at home. Thinking this was perfect timing, I bought the necessary supplies for the experiments and showed the video to the Pathfinders. To be honest, the video wasn’t a big hit, but everybody loves an edible experiment so that saved the day!
Here is what we did to create our version of tang hulurs. This makes a big batch, so you might want to reduce it. We added eight cups of sugar, which was a small four-pound bag, to three cups of water gradually, and then heated it on the stove. Do not let it boil. We did not use a candy thermometer, but you can. The mixture should change into a cloudy yellowish color with all the sugar dissolved, and should be hot to the touch. Let it cool enough to pour into a glass container. We used mason jars. You can add flavorings and/or colors at this point.
Then position a skewer in the middle, holding it in place with a clothespin laid across the top.
The skewer should be moistened and rolled in sugar to give the crystals something to adhere to.
Now you just wait for the crystals to form. That can take hours or even days; we just kept checking ours.
Break up the edges and pour out the excess liquid after it has crystallized, and set the jar in hot water to remove your creation. It’s not the healthiest treat, but fun to make to demonstrate crystals when studying rocks. Enjoy your tang hulur while reading a good book, like “Little Pear,” or even a book about rocks.
Oh, and by the way, here’s what tang hulurs really look like! Much more tasty to me!
