PREPARING BROWN STOCKS
The difference between brown stocks and white stocks is that the bones and mirepoix are browned for the brown stocks. Two methods of making brown stocks:
- Cut the bones into 3 to 4 inches piece, as for white stock. Veal and/beef are used for brown stock.
- Do not wash or blanch the bones. The moisture would hinder browning.
- Place the bones in a roasting pan in one layer and brown in a hot oven at 375°F (190°C) or higher.
- The bones must be well browned to color the stock sufficiently. This takes over an hour.
- When the bones are well browned, removed them from the pan and place in stockpot. Cover with cold water and bring to simmer.
- 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.
- 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.
- When the water in the stockpot comes to a simmer, skim and continue as for the white stock.
