Lightly coat baking sheet with cooking spray and set aside.
In a large skillet, slowly melt the caramel sauce and sugar. When melted stir in cinnamon extract and cayenne. Continue cooking until mixture reaches a temperature of 310 degrees F. Stir in pumpkin seeds until completely coated. Spread caramelized seeds onto the baking sheet and sprinkle with crushed almonds. Separate seeds with wooden spoon until cooled.
Melted sugar is very hot. Please use extreme caution when handling and pouring. Pumpkin seeds may be purchased already roasted. If using the seeds from a jack-o-lantern, rinse and clean seeds. Place on a baking sheet, lightly coated with cooking spray, in a preheated 250 degree F oven. Roast seeds for about 1 hour stirring every 15 minutes. The actual seed of the pumpkin is inside the hull. The hull is edible.
