  6. Drain the reserve the fat from the roasting pan. Deglaze the pan by adding water and stirring over heat until all the brown drippings are dissolved or loosened.  Add to stockpot.
  7. While the stock is getting started, place the mirepoix in roasting pan with some of the reserved fat and brown the vegetables as well in the oven.
