First, peel, core and chop the apples. The smaller the pieces the faster they will cook. 

Place the apples, water and lemon juice in a medium saucepan and bring to a boil. Cover with a lid and lower the heat. Let them cook until the apples are tender, around 15-20 minutes. 

Once the apples are done, let them cool before mashing. For a chunkier consistency, you can use a potato masher. And for a smoother texture, blend it in your food processor or use an immersion blender.

Let it cool and store in the fridge for a week. You can also freeze leftover applesauce in freezer bags for months.
