Donuts

1 Tbsp vinegar - 1 & 1/2 oz Milk - 1 Tbsp shortening - 1/4 cup white sugar - 1/2 egg - 1/4 Tsp vanilla - 1 cup sifted flour - 1/4 Tsp baking soda - 1/8 Tsp salt - 1/4 cup fine sugar for dusting

Stir the vinegar into the milk, and let stand for a few minutes until thick.
In a medium bowl, cream together the shortening and sugar until smooth. Beat in the egg and vanilla until well blended. Sift together the flour, baking soda, and salt; stir into the sugar mixture alternating with the vinegar and milk. Roll dough out on a floured surface to 1/3 inch thickness. Cut into doughnuts using a donut cutter. Let stand for about 10 minutes.
Heat the oil in a large deep skillet to 375ºF (190ºC). Fry doughnuts in the hot oil until golden, turning over once. Drain on paper towels. Dust with confectioners' sugar while they are still warm, and serve immediately.
