This is one of the easiest ways I know to work with sugar and create beautiful flowers. You can make as many colors as you would like. You can combine different shapes to make multicolored flowers. Have fun and let your creative instincts guide you.
Make sure the molds are clean and dry. Place molds in freezer for at least 10 minutes before filling. Cook the sugar, corn syrup and water to light caramel color (about 320 degrees F). Divide the caramel into 2 heatproof glass bowls. Add a few drops of food color to each bowl. You can use any color that you like.
Dip the flower mold into the hot sugar. I dipped the flower molds in the red sugar and the leaf mold into the green. Set the sugar coated mold onto a silpat lined baking sheet. Repeat this process using the other molds. After a few minutes, the sugar will set and cool. To remove the sugar flower from the mold, gently push at the edge of the flower. It should pop off from the mold. Repeat the same process until you have made as many flowers as you want for your centerpiece.
If you want to stick different shapes together, use more melted sugar to "glue" the pieces into place.
Remember, the sugar is very hot and will burn if it comes in contact with your skin. It is a good idea to keep a bowl of cold water readily available. If you get any sugar on your skin, dip your skin in the cold water to stop the burn and easily remove the sugar.
