Rock Candy

Rock Candy

I have one late entry for the last Cupcake Book Club. After reading Sweet Shop of Dreams and all of Jenny’s descriptions of classic British sweets, I knew I wanted to make a classic American candy. It’s late because it takes about ten days for the sugar crystals to grow.

I’ve made candy before but I’m no expert. If you’re interested in candy making and working with sugar then I wholeheartedly suggest getting Sugar Baby.

I’ve provided the bare basics here. For more details the book is well worth it. Most important rule of candy making is don’t burn yourself with hot sugar. So please be careful and don’t blame me if you burn yourself!


Rock Candy

2-4 sticks

Rock Candy


2-4 deep glasses or mugs

Weights (I used non lead washers)

4 cups sugar

2 cups water

gel color of your choice


  1. In a large pot dissolve the sugar over medium low heat. Once dissolved remove from the heat and set aside to cool completely.
  2. While the sugar syrup cools prepare the strings. Tie one end around a pencil and tie a non lead based weight to the other end.
  3. Once the syrup is cool dip the strings in and roll them in some granulated sugar. Leave the strings out for 24-48 hours to dry.
  4. Pour the sugar syrup between the mugs and place the strings inside with the pencil on top to keep it suspended.
  5. Leave for 7-10 days. give the string a wiggle every few days to keep it from sticking. Also not a good idea to do this in summer when it's humid. After a few days of the string being submerged I cut away the weights.
