Lightly grease an 8x8" baking pan and line with parchment paper with overhangs on opposite sides. Set aside.
In a large, nonstick pot, combine cream, corn syrup, sugar, butter, and boiled cider. Bring the mixture to a boil over high heat, stirring to dissolve the sugar. Reduce to medium-high heat and cook without stirring until the candy thermometer reaches 248 °F (120 °C). It will take about 20-30 minutes depending on your stove and pot.
2 cups heavy cream, 1 cup light corn syrup, 2 cups sugar, 6 tablespoon unsalted butter, 1/2 cup boiled cider
Remove the pot from the heat and stir in the salt and apple pie spice.
1/2 teaspoon salt, 1 teaspoon apple pie spice
Carefully pour the mixture into the prepared pan and let it stand for 12-18 hours at room temperature before cutting into 1" squares.
When cutting the caramels, run a very sharp knife under hot water until it's warm to the touch then spray both sides with cooking spray and cut caramels in a sawing motion.
