Combine apples and water in saucepan; bring to a boil. Cover, reduce heat, and simmer for 30 minutes or until tender. Remove from heat and let cool, mashing slightly if pieces are large. Stir in sugar and butter; set mixture aside.
**(If using fresh apples: For the filling: Add 2 TBS butter to a large saute pan and melt. Add 4 peeled, cored and chopped apples, sugar, cinnamon, and 1 tsp lemon juice and cook over medium heat until the apples are soft, about 15 minutes. Remove from the heat, mash slightly and cool.)
Roll each biscuit into a 5-inch circle on a lightly floured surface. Place about 1 tablespoon apple mixture on half of each biscuit circle. To seal pies, dip fingers in water and moisten edges of circles. Fold in half, making sure edges are even. Using a fork dipped in flour, press edges firmly together to seal.
Pour oil to a depth of 1/2 inch into a heavy skillet, or use deep fryer. Fry pies in hot oil (370°) over medium-high heat until golden, turning once. Don't rush it because you want to make sure the biscuit is cooked completely through.
