Fleur De Sel Caramels
Line the bottom of an 8-inch square baking pan (or loaf pan) with parchment paper, then brush the paper lightly with oil (or lightly cover with cooking spray), allowing the paper to drape over 2 sides.
In a deep saucepan (6 inches diameter by 4 1/2 inches deep) combine the sugar, corn syrup, and 1/2 cup water and bring to a boil over medium-high heat. Continue to boil until the caramel is a warm golden brown color. Don’t stir – just swirl the pan to mix. Watch carefully, as it will burn quickly at the end!
When the caramelized sugar is the right color, very slowly add the cream mixture to the caramel while stirring – it will boil up violently. Stir in the vanilla with a wooden spoon and cook over medium heat for 5 to 10 minutes, until the mixture reaches 248 degrees F (firm ball) on a candy thermometer. Very carefully (it’s hot!) pour the caramel into the prepared pan and refrigerate until firm.
