Fruit roll ups are made from fruit puree, which is made by crushing fruit and removing the seeds and skin. The puree is then mixed with sugar and other ingredients like lemon juice or corn syrup, and spread into thin sheets. These sheets are then dried in a dehydrator or oven, which removes the moisture and leaves behind a sticky, chewy sheet of fruit roll up. Fruit roll ups are a popular snack for both children and adults, and can be made with a variety of different fruits, including strawberries, raspberries, and blueberries.
