Ingredients for the Brown Stock

4 pounds of beef bones, preferably with some meat attached 1 pound of mirepoix (a mix of onions, carrots, and celery, typically in a 2:1:1 ratio) 1 tablespoon tomato paste 2-3 cloves of garlic (optional) 1-2 bay leaves 5-6 sprigs of fresh thyme or 1 teaspoon dried thyme 10-12 whole black peppercorns Water enough to cover the bones by about an inch

Ingredients for the Demi-Glace

2 cups of prepared brown stock 2 cups of red wine (dry varieties like Cabernet Sauvignon or Merlot) (Optional) Additional seasonings or herbs to taste

Step 1: Prepare the Brown Stock

Roast the Bones

Preheat your oven to 400°F (200°C). Place the beef bones on a roasting pan and roast them for about 30-45 minutes until they are well-browned.

Prepare the Mirepoix

In a large stockpot, heat a little oil over medium heat. Add the mirepoix onions, carrots, and celery, and sauté until lightly browned (about 10 minutes).

Combine Ingredients

Add the roasted bones to the pot with the mirepoix. Add the tomato paste and cook for a few minutes to caramelize it slightly. Stir in the garlic, bay leaves, thyme, and peppercorns.

Add Water and Simmer

Pour enough cold water into the pot to cover the bones and vegetables by about an inch. Bring the mixture to a boil, then reduce the heat to low and let it simmer gently for 6-8 hours. Skim off any foam or impurities that rise to the surface periodically.

Strain the Stock

After simmering, strain the stock through a fine-mesh sieve or cheesecloth into another pot. Discard the solids.

Step 2: Make the Demi-Glace

Combine Stock and Wine

In a saucepan, combine 2 cups of the strained brown stock with 2 cups of red wine.

Reduce

Bring the mixture to a simmer and reduce it over medium-low heat until it thickens and reduces by half (which should take about 30-45 minutes).

Final Reduction

Continue to simmer until it reaches a sauce-like consistency. You can further adjust the seasoning to taste at this point.

Optional Strain Again

To achieve a smoother texture, strain the demi-glace once more through a fine-mesh sieve.

Cool and Store

Allow the demi-glace to cool. Store it in airtight containers in the refrigerator for up to a week or freeze it for longer storage.

Tips and Flavor Variations

You can experiment with adding herbs like parsley or additional spices according to your preference. This flexibility allows you to tailor the flavor to your dish. Demi-glace can be used as a base for sauces or as a rich addition to soups and stews.

Enjoy your homemade demi-glace! It’s a versatile sauce that can elevate many dishes, from hearty stews to elegant main courses.
