Combine all the remaining dry ingredients together:2 1/2 cups of all purpose flour
1 tablespoon of sugar
2 teaspoons of salt
1 tablespoon of baking powder
1 teaspoon of baking soda
Pour the dry ingredients into the wet ingredients that sat out on your counter overnight.
Your dough should be sticky, but you may need to add small amounts of flour until you can get it out of the bowl and onto a well floured countertop.
Knead the dough just enough to get it mixed well, but do not overdo it. The more you knead it, the more air you will remove from the dough which will cause your biscuits to be dense. Your dough should be sticky inside.
Roll out your dough to about 3/4 inch thick on a floured countertop using a well floured rolling pin. It's important to roll it out thick because this is how your fluffy layers will happen. If you roll it out thinner, it will still be good and you may get more biscuits.
Once you have your dough rolled out, take a mason jar or a round cookie cutter and cut out circles from your dough. Place them on a cookie sheet that has been sprayed with non stick cooking spray, or place them in a very buttered cast iron skillet.
Bake in a preheated oven at 350 degrees. Check biscuits at 12 minutes, and add more time if needed. Biscuits should be fluffy but not undercooked.
