  • food coloring (optional)

  1. * Candy flavoring is carried by a lot of grocery stores, near the baking aisle with candy-making and cake decorating supplies.
  2. Bring the water to a boil in the saucepan.
  3. Remove from heat; add 3 cups of sugar, stirring until dissolved.
  4. Slowly add the remaining sugar, reheating the water if necessary.
  5. When all the sugar is dissolved, pour the mixture into 3 heat proof jars or glasses.
  6. Stir 3 drops of liquid food coloring and 1/2 teaspooon candy flavoring into each jar.
  7. Tie each length of string around a pencil.
  8. Lay one string on top of each jar so the strings hang down into the liquid.
  9. Crystals will begin to form in 1 hour, and continue to solidify for several days.
  10. If a layer forms on the surface of the jar, break it.
  11. When liquid completely evaporates, candy is ready.
