No sugar, no artificial preservatives…just fruit. You can use any fruit really. This one contains strawberries, pears, banana and lime. We seal them with puppy stickers or little sharpie drawings of puppies or Peppa Pig or stars. It takes a little bit more time but you don't need to be wiz in the kitchen. It’s worth it just for the smell that will fill your house as they dry in the oven.
