Preheat oil in either a large Dutch oven
or deep-fryer to about 365 degrees F.
In a large bowl mix together flour, salt and baking powder. In a small bowl, using a hand mixer
, beat the shortening
and sugar together until light and fluffy. Add in the egg and vanilla extract
. Combine the lemon juice
and the milk together in a small bowl, and add to the egg
mixture. Stir in the flour mixture and combine well to create the doughnut batter
. Allow to rest for 5 minutes.
Roll the dough out on a floured surface to about 1 to 2-inch thickness. Using a 2 1/2-inch pastry
cutter, cut out doughnuts
. Allow to rest for another 5 minutes, then fry
in hot oil, in batches, until golden brown. Remove from the oil and drain
on paper towels. Coat with cinnamon-sugar and place on a serving platter.
