New Orleans Bacon Pralines
Special equipment: candy thermometer
Preheat the oven to 400 degrees F. Line 1 rimmed sheet pan with heavy foil and another with parchment paper.
Place a baking rack over the foil-lined sheet pan and arrange the bacon slices across the rack next to each other, but not overlapping. Bake until crispy, 15 to 18 minutes. When cool enough to handle, finely chop and set aside.
Reduce the oven temp to 350 degrees F.
In a small saucepan over moderate heat, melt 3 tablespoons butter and 3 tablespoons brown sugar, about 1 minute. Add the pecans and combine until the pecans are coated. Pour out onto another unlined sheet pan and bake until golden brown, about 10 minutes. Let cool.
Place the remaining 2 cups brown sugar into a 3-quart heavy saucepan, being careful to not get sugar on the sides of the pan. Add the cream, the remaining 2 tablespoons butter and salt and cook over very low heat (do not let simmer), stirring frequently with a rubber spatula, until the sugar is dissolved, 10 to 15 minutes. Wash down any sugar crystals on the side of the pan with a pastry brush dipped in cold water. Clamp on a candy thermometer to the saucepan and boil the syrup over moderately-high heat until it registers 236 degrees F.
Remove the pan from the heat, leaving the thermometer in place, and let cool until the syrup registers 220 degrees F, 1 to 2 minutes. Using a rubber spatula, stir in the bacon and pecans. Working quickly, drop 1 tablespoon of pralines onto the prepared parchment-lined sheet pan. If the mixture starts to harden, place back on the stove over moderately-low heat and let it melt. Let the pralines sit until they harden, about 45 minutes.
