I have not (yet) made this, but my mouth waters every time I read it! I love butterscotch.

Apple Pie Filling With Vanilla & Buttershots

Recipe #259671

This can top ice
cream waffles, pan cakes, french toast. Make an apple pie with it or
stuff puff pastry with it. Pour it over a hot ricotta cheese cake.

5 quart jars

2 cups sugar
1/2 cup cornstarch
1/2 tablespoon cinnamon
1/2 vanilla bean, split and scraped
4 1/2 cups water
1/2 cup butterscotch schnapps
1 tablespoon fresh lemon juice
1/2 teaspoon lemon zest
4 lbs apples, peeled, cored and sliced
In a large pot place first 5 ingredients, bring to a boil and cook
till thick and bubbly. Stirring so it doesn`t stick to the bottom
and burn.
Meanwhile pack 4-6 slices apple in quart jars.
Remove from heat and add the lemon juice and zest and buttershots.
Pour over apples removing as much air as you can. This is thick so
use a butter knife to help it seep down to the bottom.
Wipe rims and place hot lids and rims on.
Process in a water bath for 20 minutes.
