My routine is to cook it in the evening, put it on the front porch (enclosed) and stir when I get up the next morning. I still use a paddle machine. The porch is cooler than the rest of the house so it cools a bit faster. Biggest problem is the winter when the porch is usually well below freezing. I may have to bring the syrup inside the house for a couple of hours before it is stirred. I boil the syrup in the paddle machine pan.
