1Preheat Oven 350 degrees:
Butter a tart pan or pie plate.
Combine the pineapple, brown sugar, butter, cinnamon and vanilla in a bowl and mix. Set aside while preparing the dough.
Combine the milk with the vinegar and let sit while mixing the other ingredients for the dough.
In a medium size bowl, combine the sugar, flour, butter, salt and brown sugar. Slowly, add the sour milk, stirring the mixture while adding the milk. Work the mixture into a dough; which will be sticky.
