On top of a double-boiler over hot water, add brown sugar. Butter bread slices, dice into cubes and sprinkle over sugar. Add raisins. Beat eggs with milk, stir in vanilla and salt. Pour over bread but do not stir. Cook over simmering water for one hour.
To make the sauce, combine 1/2 cup butter, 1 cup sugar, and 3 tablespoons water in a saucepan. Heat until sugar dissolves. Beat together 1 egg and sugar mixture, adding small amounts of the mixture at a time. Return egg mixture to hot saucepan, stirring constantly. Add bourbon to taste and serve over warm bread pudding.
