Butter your silicone lollipop mold. Then set aside but close to the stove.
Cut the butter into pieces and put it in your saucepan over medium heat.
5 oz unsalted butter or 10 tbsp
Right after the butter has melted, add the sugars, corn syrup, and salt. Stir well using your heatproof spatula, and let it boil. Keep stirring.
4 oz sugar or 1/2 cup, 1 oz light corn syrup or 4 tsp, 1/2 tsp salt, 4 oz brown sugar or 1/2 cup
Measure the temperature with a digital thermometer. Carefully add the heavy cream when it reaches 120 degrees Celsius. Don't stop stirring! Be delicate.
4 oz heavy cream or 1/2 cup
Continue stirring until it reaches 146-147 degrees Celsius. Then, gently pour the candy into the previously buttered silicone lollipop mold.
Use your spatula to help the whole candy pour out, but without forcing it. Just let it flow.
Let it cool for about 2 minutes, then put your lollipop sticks inside the hard candy.
Let the lollipops cool for about an hour or so before removing them from the mold, they need to be completely firm when you do that.
It is very important that once you unmold your lollipops, keep them in a dry place overnight.
And voilà! You'll be able to enjoy your candies the next day! Just be patient.
