ISO: Tried and True Cherry Pie Filling

Hi Folks,  Does anyone have a great recipe for cherry pie filling?  I will be used jarred sour cherries and would like the filling to have very little jelly when all is said and done.  I will be using it to make a chocolate cake for my son’s birthday.  He wants a Black Forest cake so the filling can’t have too much jelly in it as it will saturate the cake.  Thanks to all who reply.
