Place the eggs in a mixing bowl and beat them on medium speed until they are light and fluffy. Add the shortening and beat the mixture until the shortening and eggs are well blended. Whisk the flour, sugar and salt together in a separate mixing bowl. Set a third mixing bowl on the counter next to the bowl containing the dry ingredients. Position the sieve or sifter over the third bowl and pour the dry ingredients through it and into the bowl. Create a well in the center of the dry ingredients by pushing the dry ingredients against the sides of the bowl with a flat plastic spatula. Pour the wet ingredients into the well that you created. Fold the dry ingredients and the wet ingredients together using the spatula, being careful not to over mix. Evaluate the dough.
Use either a stand mixer with a paddle attachment or a handheld mixer.        The dough should be easy to handle. However, if the dough is too soft or sticky, fold in an additional tablespoon of flour.
