Rock Candy Recipe (Be a rock star!)

If you love sweetness, you probably already have a soft spot for rock candy.  It’s sweet.  It’s sparkly.  It’s fun to eat.  And it’s easy to make at home where you can choose the flavor & color of your candy.

Prep Time: 5 minutes

Cook Time: 5 minutes


Note:  Wait Time for big crystals is 3-7 days


  • 4 cups sugar
  • 1 cup water
  • Food coloring (optional)
  • 1/2 tsp to 1 tsp flavoring oil or extract (optional)
  • Clean glass jar
  • String, cut into 6-inch lengths
  • Pencil


In a medium saucepan, heat 2 cups of the sugar and the water. Do not boil! Stir until the sugar is completely dissolved. If you like, gradually add a few drops of the food coloring of your choice and/or 1/2 tsp to 1 tsp of flavoring oil or extract.  Add the additional sugar, stirring continuously until all the sugar is dissolved.

Pour the solution into a clean glass jar and tie the pieces of string to the pencil and suspend them across the mouth of the jar so that the ends hang into the sugar water.

Crystals suitable to eat will form in an hour and continue for several days to a week. Pieces can be broken off and eaten after the first hour. (But, try to hold out for big crystals!)

Although you may see quick results in small measure, the larger rock candy crystals you’re accustomed to seeing in the candy store will take roughly 3-7 days to form.  Have fun!!!

Yield: 12 ounces

  5. I had a rather hard time chioosng just one type of physician I would want to work for. So many of them fascinate me, and with me not really going into any medical field other than support, I never gave this any thought in the past. After reading the list, I am more favorable of working for a neonatologist. It is difficult to think about how neonatologist physicians sometimes have the most difficult job in the world, but I can only imagine how amazing it would be to be a part of saving a baby’s life. I had a coworker once whose baby was born at 36 weeks, and her baby had a lot of heart and lung problems. There were concerns about whether or not they would ever fully develop once she had him, but after many months in the NICU, and many scares that happened during it, the doctors were able to save him and he is now a very healthy 5 year old. It is because of that I have a higher interest in the neonatologist field.I hate to say which type of physician I would care less to work for, and it is because I worry that many will take it the wrong way. When I was 16, I used to help my mom at an assisted living home as a caregiver. We would get to work at 7:00 A.M. every morning to prepare breakfast for four of the elderly men and women that we were caring for. We would then make sure that all bedding was changed, rooms were cleaned, meals were prepared, and appointments were handled. We worked 12 hour days, and they were always grueling. The owner of the home made sure that everyone had their medicine and made it to their doctor appointments on time. However, she was more worried about getting paid for her services than actually helping the elderly. She would yell at them if they did something wrong, and even call them terrible names. My mom reported her and we both quit our job, but it has always left a sting in my heart since then. It is because of my experience with that situation that I do not think I could ever work for a gerontologist. I know that the situations would be much different, but ever since my experience with caring for elderly individuals it is very hard for me to think about assisting a physician in geriatrics because I worry that someone else might treat the elderly in the same way the owner of the home did. I am a firm believer that the elderly deserve the ultimate care and comfort when going through any treatment and aging in general, but I do not think I could ever work in that environment again.
