Blueberry Sauce

• Combine the blueberries and vanilla sugar in a large heavy saucepan. Add 1 cup water and the lemon juice and bring to a boil over high heat, stirring occasionally. Reduce the heat and simmer for 15 minutes, or until the mixture begins to thicken.
  
• Serve hot or allow to come to room temperature, cover and refrigerate.
• Preheat oven to 400 degrees. Position rack in middle of the oven. Arrange bread in a single layer in a baking dish. Whisk together cream, eggs, vanilla, salt. Pour over the bread and soak, turning occasionally until most of the liquid is absorbed but the bread is not falling apart. I think I ended up soaking about 30 minutes, but it may not take that long depending on the bread you may be using.
• Heat an iron skillet to high heat, but not smoking hot. Add 2 tablespoons butter at a time and add about 2 pieces of the soaked bread at a time until golden brown and crisp. Add more butter, and fry the remaining bread. If all the bread will not fit into the skillet, place on a sheet pan. Place the sheet pan in the oven and bake until puffed.

  Remove from the heat and dust with confectioner's sugar, maple syrup, blueberry sauce if you are using, and whipped cream if you are using! Enjoy!
