- Preheat oven to 450 degrees F (230 degrees C). Place veal bones in a roasting pan.
- Roast bones in the preheated oven until well-browned, about 75 minutes.
- While bones are roasting, drizzle oil onto a baking sheet. Spread onion, carrots, and celery onto baking sheet; spread tomato paste over the vegetables and mix to coat.
- Roast vegetable mixture in the preheated oven until vegetables are well-browned, about 45 minutes.
- Transfer vegetable mixture and bones to a large stockpot. Pour 10 quarts water into stockpot.
- Pour 2 cups water into the bones roasting pan, set the pan over high heat, and bring to a boil while scraping the browned bits of food off of the bottom of the pan with a wooden spoon. Pour liquid into the stockpot with the bones.
- Bring bones, vegetables, and water in the stockpot to a boil, reduce heat to low, and simmer gently, skimming foam as necessary, until meat and all connective tissue is completely off the bones, about 18 hours.
- Set a colander over a bowl and ladle vegetables, bones, and meat into colander. Discard vegetables, bones, and meat; return any broth to the stockpot.
- Bring broth to a boil; cook at a boil until liquid reduces to approximately 1 gallon in volume, 30 minutes to 1 hour.
- Strain broth through a fine-mesh strainer into a large container set in an ice bath; chill to room temperature. Cover the container with a lid or plastic wrap and chill in the refrigerator until demi-glace is cold and set, 8 hours to overnight.
- Scrape and discard any fat from the surface of set demi-glace. Turn demi-glace out onto a work surface. Cut into 16 blocks, wrap each block in plastic wrap, and place wrapped blocks in a resealable plastic bag. Store in the freezer.
- Cook's Note:
- While the stock simmers very, very gently for 18 hours, the level will drop a few inches in the pot, which is fine, but if it seems like the liquid level is getting low, add a few cups of water in.
- The nutrition data for this recipe includes the full amount of bones and vegetables. The actual amount of bones and vegetables consumed will vary.

Like HappyGenny said, it is somewhat daunting, but worth the effort. I too used a Slow Cooker over night and then transferred it into a large stock pot in the a.m.. Worked OK but keep in mind ...
Chef John is hysterical and fun! great directions in a playful way. First time making Demi-Glace and turned out great with beef bones - will; try the "cheaters" version next.
