In a large bowl, combine dry ingredients.
Add in the shortening or butter and mix until crumbly. (You can use a stand mixer or food processor to save time and effort).
Add in the milk and mix until a shaggy dough ball forms.
Roll dough onto a floured surface and cut it into several biscuits, being careful not to twist the biscuit cutters, as that can create flatter biscuits (just press the biscuit cutter down and pull it right back up again).
Combine scraps, roll them out again, and cut more biscuits — continuing this process until all the dough is used up.
Preheat oven to 450ºF and let biscuits rise while the oven preheats (or freeze for later — see instructions below).
Bake in preheated oven for 8-12 minutes.
Enjoy with butter, honey, and/or jam!
