Reduction sauces have a coating consistency. Reduction sauces are prepared by simmering juices, wines, or other alcoholic beverages over low to moderate heat to thicken and develop their individual characteristic flavors. Reducing liquids to create this type of sauce not only serves to enhance the desired flavor of the ingredient, but may also concentrate undesirable characteristics. For this reason, be careful when selecting ingredients for a reduction sauce, as some do not reduce successfully.
