Add sugar, water and, corn syrup to the pot.
Stir with a spatula until the sugar, water and, corn syrup are well combined
Turn on the heat to a medium setting
Avoid stirring the sugar once the heat is on. As the sugar heats up it will turn into a hot liquid - be careful not to get burned
As the sugar bubbles up, swirl the pot gently to even out the heat in the sugar
While the sugar is heating up, you can warm up your cream in the microwave or double boiler (Ensure that you can still see the sugar - pls do not walk away from your sugar while it is cooking)
The sugar will change color from a light-colored liquid, to an amber color and then golden color. Continue to swirl so that the sugar evens out and doesnt burn
Once the sugar achieves a dark golden color, pour the warm cream into the sugar and whisk vigorously (at this point the sugar cream mixture will bubble up furiously)
As you whisk, add the salt, pure vanilla extract, and butter
Continue to whisk vigourously until the caramel becomes smooth and silky
Pour the caramel into a mason jar and let it cool completely before using
