Preheat oven to 350 degrees Fahrenheit. Boil a pot of water and add peaches to boiling water for 30 seconds, then place in ice cold water. Peel and slice/cut peaches into chunks and set in a large bowl. Add lemon juice, cinnamon, sugar, and flour to the sliced peaches. Mix well and set aside. (Allow mixture to sit for 5 minutes)
