To make the yolks you will need:
Two aluminum baking sheets
1 cup Light corn syrup
1 cup sugar
1/2 cup water
First you will need to fashion some simple circle candy molds. Do this by cutting the edge off of the baking sheets. Then cut a 1 inch wide strip off of the sheet lengthwise. Next cut the strip into thirds. Fold over one of the sections and secure it with a paperclip. Repeat this process until you've made as many molds as you would like or until you use up your baking sheets. Now set the molds on a sprayed baking sheet and gently press the tops to make sure there are no large gaps at the bottoms. Now make your candy to fill the molds.
In a saucepan combine sugar, syrup, and water and bring to a boil on medium heat. While stirring it frequently let it boil until it reaches hard crack stage. (300* on a candy thermometer) When it has reached this stage pull it off of the heat and quickly stir in your Lemonade packet.
OPTIONAL: Depending on the lemonade the color may vary. You can add some yellow food coloring to darken it if you would like.
Working quickly, fill each mold with about a tablespoon of candy. Once the yolks have cooled completely, remove the molds & tap off any extra pieces with a butter knife.
Now you have some perfect little yolks. Moving on....
