In a large pot, melt the butter over a medium high heat. Let the butter cook until it starts to lightly brown.
Once the butter has begun to brown, add the brown sugar and stir it, combining it with the butter
Lower the heat to medium and cook the sugar until it begins to melt and bubble
Add the apples, bourbon, cinnamon, and salt
Cook the apples over a low heat until they soften and can be mushed, about 30 minutes. Using the back of a wooden spoon, smash the apple chunks to desired consistency. As the juices are evaporating, add the water and mix. Add additional sugar, cinnamon, or bourbon if preferred
Once the apples have reduced to sauce-like consistency, shut the heat off and let cool. If you prefer a smoother texture rather than chunky, once it has cooled, you can use an immersion blender or regular blender to puree
Serve and enjoy! You can also refrigerate for up to a week and enjoy later
