Ingredients for Demi-Glace

Method

Instructions for Making Demi-Glace

  1. 1

    Roasting the Bones

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

  2. 2

    Preparing the Stock

    Transfer the roasted bones to a large stockpot. Add onion, carrots, celery, garlic, and tomato paste. Pour in the red wine and allow it to simmer for about 10 minutes.

  3. 3

    Simmering

    Add water to the pot, ensuring the bones are covered. Bring to a boil, then reduce to a simmer. Skim off any foam that rises to the surface. Add bay leaves, thyme, and peppercorns. Simmer for at least 4 hours, preferably 8-12 hours for a richer flavor.

  4. 4

    Straining

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

  5. 5

    Reducing

    Return the strained stock to the stove and simmer on low heat until it reduces to about half its original volume. This will create a thicker, more concentrated demi-glace. Season with salt to taste.

  6. 6

    Cooling and Storing

    Allow the demi-glace to cool before storing in airtight containers. It can be refrigerated for up to a week or frozen for later use.
