Add all ingredients into large pot over medium high heat. Cover and bring to boil then lower temperature to low and simmer for at least 30 minutes. Note: This also works great with a crockpot (high to boil and low for 30+ minutes)
Once the apples get a soft and mushy remove lemon peels and mash with a potato masher. For a less physical approach an egg beater (personal favorite), immersion blender, food processor, or blender (pulsing) can smooth things out real quickly
