Before you begin, preheat your oven to 425 degrees. You'll want a nice hot oven in order to get a quick rise from the steam produced by the butter in your homemade biscuits.
In a large bowl add all of your dry ingredients; flour, sugar, baking soda, baking powder, and salt. Whisk them all together to incorporate.
Using a cheese grater, shred cold butter into your dry ingredients. If you don't have a grater, you can use a knife to chop your butter into small pieces. Cut it in using a pastry cutter or a fork. Make sure it's well incorporated.
In a medium bowl stir together the sourdough discard and half & half. Placing them in the bowl together will thin your discard that is likely thick and cold straight from the fridge.
Pour wet ingredients into the dry flour mixture and mix together using your hands. Don't try to avoid getting your hands messy. Using your hands to mix is the best method for incorporating all of the ingredients. A shaggy dough will begin to form. Keep mixing until there are no dry bits of dough.
Begin rolling out your dough on a lightly floured surface. Roll it out just enough to fold it like a letter and then roll it out the rest of the way. ( Be sure to watch my video below to see how this is done.) Do not skip this step! Folding your dough allows pieces of butter to stack and creates beautiful flaky biscuits.
Now finish rolling out your biscuit dough and use your pizza cutter to shape perfect sourdough biscuits. Of course, you can always use a biscuit cutter, but I find that I waste less dough using my pizza cutter. Surprisingly enough, thick rectangle biscuits taste just as good as round ones.:)
Place biscuits on a baking sheet lined with parchment paper or greased baking sheet and bake for about 15 minutes until golden brown. You can also bake these in a cast iron skillet if you want to up your homesteader game.
This sourdough biscuit recipe will produce the most tender flaky sourdough biscuits you've ever had and is a delicious way to use your sourdough starter discard.
Serve them with sausage gravy, or melted butter and jelly. One of my family's favorite ways to enjoy this recipe is to drizzle honey butter on top. This is easy to make by just stirring together softened butter and a little honey. This is also my go-to recipe for a last minute bread to serve with soups, stews, or other savory meals.
