When you are ready to cut the caramel, lift the caramel from the pan using the foil as handles. If you have used heavy-duty foil you can cut the caramel while it is in the foil (as the picture demonstrates). However, if you have used regular foil, the foil will be cut along with the caramel and you will have to peel squares of foil off of the bottom of every single caramel candy. To avoid this tedious task, place a piece of waxed paper on the counter. Flip the top of the caramel onto the waxed paper and peel the foil layer from the bottom of the caramel.
Spray a large knife with nonstick cooking spray. Firmly cut into the caramels, creating 1” squares. Wipe the blade and re-spray as necessary.
