Preparation

Step 1

Combine all of the ingredients in the saucepan and stir until the sugar is completely moistened. Clip the candy thermometer to the side of the pan and set the pan over high heat. Do not stir the sugar after this point.
As the sugar comes to a boil, dip the pastry brush in a dish of water and brush down the sides. This dissolves any sugar crystals on the sides of the pan that could cause the syrup to re-crystallize. Once the syrup comes to a full boil, you don’t need to brush the sides anymore. (If you don’t have a pastry brush, you can also cover the pan with a lid for two minutes just as the sugar comes to a boil. The steam trapped in the pan will wash any crystals from the sides.)
Boil the syrup until it just barely reaches a temperature of 240° Fahrenheit (in other words, its better to be a few degrees under than a few degrees over). Immediately turn off the heat, remove the candy thermometer, and carefully move the pan to a cool spot on the stove or a cooling rack. Allow the syrup to sit undisturbed until it has cooled completely, at least an hour.
Gently pour the cooled syrup into clean glass jars, seal with the lids, and store in the cupboard. Store them where they won’t be jostled too much, as this can cause the syrup to crystallize. It will keep for at least two months, but we’ve stored it for longer without any changes to the syrup.
To Use the Syrup - This syrup tends to be thicker than corn syrup and can be difficult to pour or measure. To make it a little more workable, remove the metal lid from the glass jar and microwave the jar of corn syrup on HIGH in 30 second bursts until it’s pourable. This usually seems to take a total of 1 - 1.5 minutes. Alternatively, you can put the jar in a saucepan of simmering water to warm the syrup.
One Last Note - Re-heating can sometimes cause the syrup to begin crystallizing. Because of this, we’ve found it best to store the syrup in half-pint (1 cup) jars, which is what most recipes call for. This way we can heat and use one portion at a time without leftovers.
