Apples are slowly cooked in the crock pot with sugar and spices, caramelized to make this sweet thick dark apple preserve (like a spreadable apple pie) that&#039;s great on toast, stirred into your oatmeal, Greek yogurt or cottage cheese, served over pancakes or biscuits, graham crackers, etc, and for savory dishes such as roast pork or on a sandwich. Grilled turkey and brie sandwiches with apple butter is a favorite!
