French bread croutons should be cut out of a baguette-style French bread loaf. Slices should be one inch thick.
In a cast iron skillet, combine butter, brown sugar and honey over medium-high heat. Cook mixture, stirring constantly until bubbly and sugar has dissolved. Add nuts. Pour Brulee into the bottom of a round, two-quart Pyrex baking dish. Allow Brûlée to cool slightly then top with the French bread croutons.
In a large mixing bowl whisk eggs, milk, heavy cream, cinnamon, nutmeg, vanilla and Amaretto. Pour mixture evenly over the croutons. Using the tips of your fingers, press bread down gently to force custard into croutons without breaking. Cover dish with plastic wrap and refrigerate overnight.
Preheat oven to 350 degrees.
Allow custard to come to room temperature one hour before baking. Bake uncovered until French bread is puffed and edges of croutons are golden brown, (approximately 40 minutes). Place a plate on top of the baking dish. Using dish towels or pot holders, invert dish onto a plate. Top with powdered sugar. Yield: four to six servings
