Peel, core, and chop the apples into bite-sized chunks. No drama—keep chunks even so they cook evenly.
In a medium pot, add apples, water, lemon juice, cinnamon, and salt. Bring to a simmer over medium heat.
Cook, uncovered, for 15–20 minutes until apples break down and smell amazing. Stir occasionally to prevent sticking.
Mash for a chunky texture or use a blender for a silky smooth sauce. If the sauce is too thick, splash in a little more water and blend again.
Taste and adjust sweetness or spice. Add sugar or maple syrup a little at a time until you love it.
Cool slightly, then store in airtight jars in the fridge for up to a week or freeze for longer adventures.
