Prepare Pastry; divide in two portions, about two-thirds in one portion and one-third in other. Roll out the larger portion and line a shallow 1 1/2 quart baking dish (about 10x6).
Melt butter in a medium saucepan; add flour and seasonings and stir until smooth and bubbly. Add liquids and cook slowly until thickened; add chicken. Pour into pastry lined pan.
Roll out remaining pastry; cover chicken mixture; pinch edges together. Bake
at 425° for 35 minutes, or until pastry is nicely browned.
