Maggiano’s Little Italy Chef Tips: How to Prepare a Demi-Glace

by Jeff Mann, Dallas, TX | Written on April 10, 2014

We love being a chef-driven restaurant. We’re a scratch kitchen, we can accommodate guests’ dietary needs, and a lot of  thought and love goes into our dishes. Recently, MaryJane from South Carolina (we don’t even have a restaurant in SC yet!) sent us a note. She tried the Delmonico Steak in our Orlando restaurant and loved the demi-glace, a rich brown sauce that accompanies the dish, so we were inspired to share our tips to prepare a demi-glace with MaryJane and you!

 

Maggiano's Little Italy Chef Tips: How to Prepare a Demi-Glace

Making a demi-glace is a very involved process that starts with a veal stock. This recipe provides step by step instructions to roast veal bones and vegetables to create a quality veal stock and turn that into a demi-glace. Please note that you’ll need lots of time, and TLC for this preparation. There are no shortcuts to making this sauce successful, but it is so worth it.

Makes 2 Cups
Ingredients
10 lbs. veal bones
3 carrots, roughly chopped
2 onions, roughly chopped
1 white part of leek, roughly
chopped (optional)
1 bouquet garni
1 (6-oz.) can tomato paste

Instructions
1. Roast the bones: Heat oven to 500°. Put bones into a roasting pan large enough to hold them in a single layer and roast until lightly browned, about 1–1 1⁄2 hours. Add carrots, onions, and leeks to the pan and spread them evenly around the bones. Roast the bones and vegetables until they are deeply browned, about 45 minutes more.

2. Deglaze the pan: Transfer bones and vegetables to a 15–20-qt. stockpot. Pour off and discard any fat in the roasting pan and place pan over 2 burners on the stove over medium heat. Add 3 cups water to pan; begin scraping up any browned bits from bottom of pan with a wooden spoon. These caramelized morsels of concentrated juice, called the fond—literally, the foundation—will enrich the stock. Simmer for 3 minutes; transfer liquid to pot of bones. Add bouquet garni and tomato paste. The paste will give the stock a deeper flavor and color. Cover bones with 6–8 qts. cold water; set pot over medium-high heat. Starting with cold water encourages the proteins and fats contained in bones to rise to the surface in large pieces, where they can be skimmed and discarded.

3. Simmer the stock: When the first bubbles begin to appear on the surface of the liquid, reduce heat to medium-low and maintain a very gentle simmer; a bubble should rise to the surface about once per second. Simmering slowly prevents the fat and impurities from being churned back into the stock and clouding it. The strength and concentration of your demi-glace will be determined by the length of time the stock simmers. For the minimum amount of extraction, it should simmer for at least 6–8 hours, but we recommend 12–24 hours for a richer, more gelatinous sauce. Check every few hours and add more cold water if necessary so that bones are always covered.

4. Skim the fat: Skim fatty froth from surface of stock with a ladle every 5–10 minutes during first hour of cooking to prevent it from clouding stock. After first hour, skim the stock every 30 minutes or so.

5. Strain the stock: When the stock is ready, set a chinois (a fine-mesh conical sieve) or a fine metal sieve over a clean 8-qt. pot. Strain stock through sieve into the pot. Tap edge of sieve with a wooden spoon to loosen any solids that impede the straining of the stock, but do not force liquid through. Discard bones, vegetables, and bouquet garni. The bones may be reused to make a lighter, secondary stock with fresh vegetables and aromatics, called remouillage and used for sauces and soups. The stock should yield 4–5 qts. If storing stock for another use, you can cool it quickly by placing the pot in a sink half filled with ice water. Once it’s cooled, skim the surface again to remove any fat. Transfer the stock you don’t plan to use right away to storage containers and refrigerate. Stock will keep refrigerated for up to 1 week or frozen for up to 6 months. To transform the stock into demi-glace, proceed to next step.

6. Reduce the sauce: Traditionally, the stock for demi-glace was thickened with a roux, but Maggiano’s chefs have used natural reductions to accommodate allergies and gluten free guests. Simmer stock over medium-high heat, skimming occasionally, for 4–5 hours until reduced to 2 cups. Refrigerate for up to 2 weeks or freeze for up to 6 months.

    You are so nice to take the time to let me know how to prepare this demi-glace; I can’t wait to get started! I know I’ll be back in your restaurant when we next go to Florida; but in the meantime, will you put in a good word for us for a Maggiano’s in Columbia, South Carolina?

    Money talks. Mine is always saying “Spend me!”Money, like a running horse, should be kept–well-in-hand.Money is the devil’s eye.Money is a sort of instinct. It’s a sort of property of nature in a man to make money. It’s nothing you do. It’s no trick you play. It’s a sort of permanent accident of your own nature; once you start, you make money, and you go on … But you’ve got to begin … You’ve got to get in. You can do nothing if you are kept outside. You’ve got to beat your way in. Once you’ve done that, you can’t help it! http://www.augustagoldira.com/gold-ira-rollover/gold-ira-rollover-guide/
