Prepare the Dough: In a large bowl or Thermomix mixing bowl, combine flour, salt, milk and water. Mixing until a dough forms. Knead about 8-10 minutes until smooth and elastic.
Cover the dough let it rest for 10-15 minutes. Meanwhile prepare the filling.
Make the Filling: In a medium bowl, mix together diced apples, sugar, and cinnamon. The filling should smell just like apple pie filling.
Roll and Fill: Roll the dough thinly on a floured surface. Cut into squares about 4 inches wide.
Place a spoonful of filling in the center of each square. Fold the dough in half and seal the edges making it in a round shape.
Steam the Manty: Lightly grease your steamer trays. Arrange the manty with space between them.
Steam for 45 minutes until the dough is tender and the filling is fully cooked.
Serve Warm: Serve warm and drizzle sour cream and sugar mixture onto the Manty. The warm apples and cinnamon filling make these irresistible straight from the steamer.
