Line a rimmed baking sheet with parchment paper.
Combine all ingredients in a medium saucepan; cover and cook over medium heat for 10 minutes, stirring occasionally, or until apples and raisins are soft. Transfer mixture to a blender; pulse until smooth.
Press mixture through a fine sieve onto parchment and discard solids left behind. (This step is optional.)
Spread mixture into an even thin layer on parchment. Heat oven to 150° on convection cook and cook for 6-8 hours or until fruit leather is just slightly sticky, but not tacky. (A regular bake setting will work too, it may just take a bit longer.)
Allow to cool completely. Cut fruit leather and parchment into desired shapes.
