Can you substitute Demi glacé for broth if you add water to it?

Yes, you can substitute demi-glace for broth by diluting it with water. Demi-glace is a concentrated sauce made from reduced stock, so adding water will help achieve a broth-like consistency and flavor. However, keep in mind that demi-glace is richer and more flavorful than standard broth, so the taste may differ slightly. Adjust the water amount based on your desired intensity.
