How To Make Demi Glace

Demi glace is a thick, rich brown sauce bursting with flavor. The increased viscosity and pronounced taste is accomplished through cooking down veal bones opposed to the usual beef or chicken. The veal bones contain more collagen than a full grown cow’s would and when cooked down for hours, the collagen transforms into gelatin, making the stock thicker and richer. To accomplish an even more in depth and darker sauce, many chefs recommend roasting the bones and vegetables together before making the stock. We definitely recommend you try it at least once! Most demi glace sauces are made by diluting Escoffier’s Espagnole sauce with some beef and/or chicken broth until it’s been reduced by half. The results are just as delicious and a lot less time consuming. It makes for a deliciously complex addition to stews, soups and other sauces as well. Like any sort of reduction, it obviously takes time and a bit of effort. But never fear, that time spent will greatly be made-up with time saved for many future dinners.
