Prepare boiling water canner or pot. 

Heat mason jars in simmering water until you are ready to use. Use simmering water, not boiling. Wash lids in warm, soapy water and set bands aside. 

In a large pot, combine the apple slices, sugar, ClearJel, cinnamon, nutmeg, salt, and water. 

Slice the vanilla bean in half lengthwise, scrape the insides into the pot.

Bring mixture to a boil over medium-high heat and stir constantly. Cook until the mixture thickens and begins to bubble. Add lemon juice and bourbon and return to a boil. Stir constantly and boil for 1 minute. 

Ladle filling into hot jars leaving 1" of space at the top. Remove air bubbles by using a spoon or spatula to move air from the edges of the jar towards the center. Wipe the rims and place the lid on the jar. Apply the band until the fit is snug, using only your fingers. 

Place the jars in the water canner for 25 minutes (adjust for altitude), then remove jars and cool. 

Check lids for a good seal after 24 hours, the lid should not pop up and down when pressed in the center.
