Preheat your oven to 425 F.
Lightly grease a baking sheet or iron skillet.
Mix the flour, baking powder, salt, and sugar together until combined.
Cut in the shortening or butter until the mixture becomes crumbly.
Add 1/2 cup milk and mix until well combined and then add the remainder of the milk. Once you have worked your mixture into a soft dough, place the dough on a floured surface.
Knead the dough adding flour as needed.
Roll it out with a rolling pin until you reach your desired thickness. I prefer around 1/4"-1/2". Use a metal biscuit cutter to cut out the biscuits.
Place biscuits on the greased baking sheet.
Bake at 425 F for about 15 minutes or until the tops are golden brown.
Enjoy the fruits (or carbs) of your labor!
