This has been a quest for me since eating at the III Forks in North Dallas a few years. I tried to duplicate the dressing but failed miserably, many times. I found this version on the Texas Monthly website & it comes darn close to the original.
This is a wonderful apple pie filling that you make in the fall when apples are in abundance. During the winter months, just pull a package of pie filling from the freezer, defrost, and pour into your favorite pie crust. This makes enough filling for 4 pies.
