In a medium saucepan, set over medium heat, add the sugar. Shake it around a bit until there’s an even layer of sugar on the bottom of the saucepan. Cook the sugar, staying close by so you can keep an eye on it, until the edges of the sugar begin to dissolve and turn a light golden brown. At this point, give it a stir until it becomes an even light brown color. Turn off the heat. Pour in the warmed heavy cream (it may bubble up a bit but that’s ok) and keep stirring until smooth. Whisk in the spices and the butter, until melted. If at any time you need to, feel free to turn the heat back on. The color should be a light to medium brown. Set the caramel aside. *Note: Right before you use it, you may need to reheat it over medium-low heat. It may seem like it turned into a big caramel candy, but reheating it and whisking it will make it super smooth and pourable again.
