Espagnole Sauce

1 gallon brown stock, hot
1 1/2 cups brown roux
1/4 cup bacon fat
2 cups chopped onions
1 cup chopped carrots
1 cup chopped celery
Salt
Freshly ground black pepper
1/2 cup tomato puree
1 bouquet garni

In a stock pot, whisk the hot stock into the roux. In a large saute pan, heat the bacon fat. Add the vegetables. Season with salt and pepper. Saute until wilted, about 5 minutes. Stir the tomato puree into the vegetables and cook for about 5 minutes. Add the tomato/vegetable mixture to the stock/roux mixture. Add the bouquet garni and continue to simmer, skimming as needed. Season with salt and pepper. Simmer the sauce for about 45 minutes. Strain the sauce through a China cap.
