Chinese Doughnuts

Directions

1. 1
   Stir the water, sugar, baking powder, baking soda, salt and alum powder together in a large bowl.
2. 2
   Let stand until small bubbles form, about 5 minutes.Stir in the flour and mix until the dough is stiff and smooth. Turn the dough out onto a lightly floured work surface. Knead, adding more flour as necessary to prevent sticking, until the dough is smooth and elastic, about 5 minutes. Cover the dough with a damp cloth and let stand, until slightly puffy and soft, about 30 minutes.Knead the dough again for 5 minutes, recover, and let stand for 30 minutes.Knead the dough briefly to remove any air bubbles. Rub the 1 tablespoon oil over the surface of the dough, then place the dough in a 2-gallon resealable plastic bag. Seal the bag, then press the dough inside the bag into a rectangle.

   Let the dough rise in a warm location of the kitchen until it puffs slightly, about for 4 hours.

   Place the dough on a lightly floured surface. Flatten and stretch the dough to make a 12- by 8-inch rectangle about 1/4-inch thick.
5. 5
   Cut the dough crosswise into 12 strips, each about 2/3- to 1-inch wide, then cut the strips in half crosswise.Form the doughnuts: stack two strips of dough, one atop the other, then press a thin chopstick lengthwise along the center of the top piece of dough to seal the two pieces of dough together.
6. 6
   Pour enough oil into a wok to fill 3 inches.
7. 7
   Heat to 350 degrees. Hold the ends of one of the doughnuts, stretch it out to about 6 inches, then carefully slip it into the hot oil. The doughnut will shrink in length then puff. Fry the doughnuts, a few at a time, turning continuously until golden brown, about 1 1/2 to 2 minutes.

   Remove the doughnuts with a wire skimmer or slotted spoon and drain on paper towels. Fry the remaining doughnuts.
