Heat oven to 350 degrees. Melt butter in a 13x9x2 inch baking dish ( I prefer to use a glass one). Cut shortening into flour until particles resemble fine crumbs. Add milk and stir with a fork only until dough leaves the side of the bowl. Turn out dough onto a lightly floured board or pastry cloth, and knead just until smooth. Roll dough out into a large rectangle about 1/4 inch think. Sprinkle cinnamon over chopped apples, then sprinkle apples evenly over the dough. Roll up dough like a jelly roll and dampen the edges with water to seal. Slice dough into about 16 slices, 1/2 inch thick. Place slices in baking dish with the melted butter. In saucepan, heat water and sugar until dissolved. Pour the sugar syrup around the rolls. This will look like too much liquid, but dough will absorb it while baking. Bake for 55-60 minutes.
VARIATION: This cobbler can also be made with other fresh, frozen, or canned fruits such as blackberries, cherries, or peaches. If the fruit is packed in liquid, drain and substitute for part of the water in the sugar syrup. Add enough water to make two cups of liquid.
