Combine sugar, corn syrup and water in a heavy-bottomed, stainless steel pot over med-high heat. Bring to a boil
Cover the mixture with the lid and let condensation build for 5 minutes (this helps to wash the sugar off the sides of the pan). Remove lid and reduce heat to medium.
Insert candy thermometer and let mixture cook (do not stir) until it reaches 300ºF.
Remove mixture from heat and stir in flavoring and colors
Let mixture cool a bit until it's thick enough to hold it's shape when poured and then pour into circles on your silicone mat (or into your candy molds). Insert your lollipop sticks and let cool completely before removing them from the mat.
Torch the back sides of the lollipops (optional) to make them super clear. Store in air-tight containers at room temperature or wrap individually to prevent them from getting sticky.
