How to Make Fudge Harden After Its Already Cooked
- 1). Cool the cooked fudge to 110 degrees Fahrenheit. Measure the temperature with the kitchen thermometer that you should have clipped to the saucepan earlier in the cooking process. Do not disturb the fudge while it is cooling.
- 2). Stir the fudge vigorously and continuously with a wooden spoon, until it becomes very thick and acquires a matte appearance. This takes about 15 or 20 minutes of non-stop stirring.
- 3). Pour the fudge into a buttered, foil-lined pan. Press it into the pan with your hands and let it cool at room temperature for several hours.
