Place them in a medium saucepan with enough water to cover them (about 1 cup). Add 1-2 cinnamon sticks depending on whether you want a subtle or prominent cinnamon flavor.
Add lemon juice.
Bring to a boil over medium high heat. Once the liquid comes to a boil, turn the heat down to medium low and allowe the apples to simmer until they're just cooked and still hold their shape. Approximately 20 minutes.*
Remove the apples from the liquid and allow them to cool for 5-10 minutes before serving.
Allow leftover cooked apples to cool to room temperature and store them in an airtight container in the refrigerator for 5-7 days.
Notes
*If you prefer the cooked apples to be more like chunky applesauce, cook them longer so they begin to break apart. **Keep the cooking liquid (stored in an airtight container in the refrigerator) and use it for cooking oatmeal to give your oatmeal a hint apple cinnamon flavor. Or freeze the apple cooking liquid in ice cube trays and use it when making smoothies.
