Apple butter is a spread made from apples. It's similar to jam or jelly, but instead of using sugar and fruit juice as a preservative, apple butter uses cider vinegar or lemon juice. The resulting product has a sweet and tangy flavor with a smooth texture. Apple butter can be used in various ways such as spread on toast, added to baked goods like pancakes or muffins, or even used as a condiment for savory dishes like roasted meats.
