In saucepan, stir together brown sugar, eggs, salt and half and half until smooth. Turn on heat and bring to a simmer, stirring constantly, and cook 2 minutes more or until mixture reaches 160F on a thermometer.
Remove from heat and pour through a sieve into a clean bowl. Stir in the cream, vanilla and salt. Let cool slightly, then cover and chill thoroughly -- overnight is best.
Before churning, add the bourbon and the buttered pecans. Churn as the manufacturer of your ice cream maker directs.
Buttered Pecans
In a small pan over medium heat, sauté pecans in butter until lightly browned, stirring frequently. Strain them out of the butter with a slotted spoon and allow them to drain and cool. Chop.
Notes
Cook time refers to chill time and is only an estimate.
