Unsweetened applesauce is a type of applesauce that does not contain any added sugar or other sweeteners. It gets its sweetness naturally from the apple itself and may have a slightly tart taste due to the presence of natural acids in the fruit. This type of applesauce can be used as a healthier alternative to processed foods containing added sugars, and is often recommended for use in baking or cooking when a sweetened version would not be appropriate.
