To make the pumpkin bread, preheat oven to 350 degrees and grease a 9X5 loaf pan and line with parchment paper. Whisk all the dry ingredients (except currants) in a large mixing bowl. Blend all of the wet ingredients in a blender. Add the wet ingredients to the dry ingredients and mix until just combined (do not overmix). Stir in currants. Pour into loaf pan and bake until a tester comes out clean, approximately 1 hour. Allow to cool completely.

Cut the bread into 1-inch cubes and dry out a little on a baking sheet overnight or toast in a 325 degree oven, turning once, for 30 minutes. Let cool before proceeding. (You can do this the day before.)

In a medium saucepan, mix the half-and-half and maple syrup and bring to just a boil over medium heat, stirring frequently.

Whisk together the eggs, vanilla and bourbon until foamy. Slowly whisk in half-and-half mixture until thoroughly blended.

To assemble the bread pudding, place the dried out pumpkin bread cubes in the bottom of a 9X13 inch baking dish. Pour the custard mixture into the dish evenly. Allow to sit for 10-15 minutes so that the bread can soak up the custard. Or allow to soak overnight in the refrigerator, covered.

Sprinkle the cinnamon over the top of the bread pudding. Place the baking dish in a large roasting pan and fill the pan with enough water to come halfway up the sides of the dish. Bake in the center of a 350 degree oven for 45 to 50 minutes, until the custard is set around the edges yet still slightly soft toward the center. Remove the baking dish from the water as soon as it’s taken from the oven. I usually do this by placing two metal spatulas underneath the baking dish to lift it out of the water bath and ask someone to help me transfer it to a trivet to cool.

To make the apple-caramel sauce:

Combine the cream, apple juice, star anise, ginger, cloves, cinnamon sticks and nutmeg in a small saucepan and bring to a simmer.

Cover and remove from the heat and let steep for at least 20 minutes. Strain the mixture into a clean, small saucepan and place back over low heat while you make the caramel.

Combine the sugar, water and vinegar in a medium saucepan over high heat and cook WITHOUT STIRRING, until it’s a deep amber color, about 8 minutes. Slowly whisk in the warm cream mixture a little at a time, and continue whisking until smooth. Add the Calvados and cook for 30 seconds longer. Transfer to a bowl and keep warm. This sauce can be made 2 days in advance and refrigerated. Reheat over low heat before serving.

Serve bread pudding warm or at room temperature with apple-caramel sauce.
