Once you try this recipe, you may never go back to canned biscuits. All three of my daughters have made these biscuits for the county fair and received purple ribbons.
Preheat oven to 450 degrees. In medium bowl, sift together flour, sugar, baking powder, cream of tartar, and salt. Cut in shortening until it resembles coarse crumbs.
In small bowl, beat egg and milk lightly. Add egg mixture to flour ingredients and mix until combined.
Turn out on floured surface and knead 10-15 times. Roll out 3/4" - 1" thick and cut with biscuit cutter.
Place biscuits on a baking sheet lined with parchment paper or a silicone baking mat. Bake until golden brown 10 -12 minutes. Remove and place biscuits on a wire cooling rack.
Makes 20-24 biscuits. Serve with jelly and/or sausage gravy.
