What is the main characteristic of a demander sauce?

The main characteristic of a demander sauce is its preparation method, which involves a reduction technique. This approach typically entails simmering a liquid, often made from stock, wine, or other flavorful liquids, until it has reduced in volume, concentrating the flavors and developing a richer consistency. This technique allows for the creation of a robust and complex sauce that enhances the dishes it accompanies.

While sauces can indeed be thickened with starches, such as cornstarch or flour, the defining feature of a demander sauce lies in the reduction process rather than simply thickening. Similarly, while a variety of spices and herbs can contribute to the flavor profile of such sauces, it is the method of reduction that distinguishes the demander sauce from others. Lastly, serving temperature might influence the experience of a sauce, but the essence of a demander sauce is fundamentally tied to its reduction-based preparation.
