Whats a good rock candy recipe?!
Answers: i need to have a recipe for a class.
4 cups sugar
1 cup water
Food coloring
Clean glass jar
String, cut into 6-inch lengths
Pencil
Instructions
In a medium saucepan, heat 2 cups of the sugar and the water. Do not boil! Stir until the sugar is completely dissolved. Gradually add a few drops of the food coloring of your choice and 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 some time to form.
hi-try going to allrecipes .com and type rock candy into the search box.they have quite a lot of different rock candy recipes to choose from.
This should help.

Did You Know?
Rock candy is one of the oldest and purest forms of candy. It was originally used by pharmacists to make medicines for many kinds of illnesses.
What Do I Do?
1. Heat the water in the saucepan over medium-high heat until it comes to a boil.
2. Completely dissolve the sugar in the boiling water, stirring continuously with the wooden spoon until the solution grows clear and it reaches a rolling boil.
3. Remove the solution from the heat, and then carefully pour it into the jar. Cover the jar with a small piece of waxed paper.
4. Tie the weight to one end of the string, and then tie the other end to the middle of the pencil. The string should be about two-thirds as long as the jar is deep. Dip the string into the sugar solution, remove it, lay it on a piece of waxed paper, straighten it out, and let it dry for a few days.
5. Gently suspend the prepared string in the solution and let sit at room temperature, undisturbed, for several days. You can check each day to see how much your crystals have grown. It’s tempting, but don’t touch the jar until the experiment is finished—it usually takes about seven days.
6. At the end of the week, the crystals on your string should be clearly defined, with sharp right angles and smooth faces of various sizes. In the field of crystallography, these are called monoclinic crystals. Their shape is determined by the way the individual sugar molecules fit together, which is similar to the way the shape of a pile of oranges is determined by the shape of the individual oranges and the way they stack together.
? Why does the string need to be soaked and then dried?
The string will provide the surface on which the crystals will grow. As water evaporates from the string, small crystals of sugar will encrust the string. These tiny seed crystals provide starting points for larger crystals. Future growth will be concentrated around these points.
? What makes the crystals grow?
Two different methods will contribute to the growth of the crystals on the string. You have created a supersaturated solution by first heating a saturated sugar solution (a solution in which no more sugar can dissolve at a particular temperature) and then allowing it to cool. A supersaturated solution is unstable—it contains more solute (in this case, sugar) than can stay in a liquid form—so the sugar will come out of solution, forming what's called a precipitate. This method is called precipitation.
Rock Candy:
Prep: 15 min., Cook: 20 min., Stand: 14 days. Crystals will form on the surface of the liquid. This is not a problem. Simply break them up, and scoop them out to enjoy.
4 (12-oz.) glass canning jars
4 (7-inch) pieces clean kitchen string
4 wooden skewers or pencils
4 1/2 cups sugar
2 cups water
10 drops red food coloring*
1/8 teaspoon cinnamon oil*
2 teaspoons vanilla extract
1. Arrange jars in bottom of a large Dutch oven, and fill with enough water to cover jars by 1 inch. Bring to a boil over medium-high heat; boil 2 minutes (this is to sterilize). Carefully remove jars with kitchen tongs to a wire rack; cool completely, and dry.
2. Tie strings around centers of wooden skewers or pencils. Place one string in each jar, resting skewer or pencil across rim of jar, and making sure strings do not touch bottoms of jars. Set aside.
3. Bring sugar and 2 cups water to a boil in a large saucepan over medium-high heat, stirring occasionally; boil, stirring occasionally, 5 minutes. Remove from heat. Stir in food coloring, cinnamon oil, and vanilla. Let stand 5 minutes.
4. Pour about 1 cup syrup mixture carefully around skewer into each jar. Loosely cover with aluminum foil (including skewer); pierce aluminum foil several times with a skewer or knife. Let stand 10 to 14 days or until crystals form on strings. (Occasionally break up hard sugar layer on surface using a wooden skewer.) Remove strings from jars, and suspend strings between jars until crystals are dry (about 1 hour). Remove strings from skewers or pencils.
*10 drops of your favorite shade of food coloring may be substituted for red food coloring, and 2 tsp. of your favorite flavored extract, such as mint, strawberry, or orange, may be substituted for cinnamon oil.
