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.

13
Wash down any sugar crystals on the side of the pan with a pastry brush dipped in cold water.

14
Clamp on a candy thermometer to the saucepan and boil the syrup over moderately-high heat until it registers 236 degrees F.
-
15
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.

16
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.
