Equipment

  • Baking Dish or Cake Pan (see notes for details)

Ingredients  

  • 300 g All Purpose Flour
  • 150 g Sourdough Starter (or sourdough starter discard)
  • 15 g Sugar
  • 10 g Baking Powder
  • 7 g Baking Soda
  • 10 g Salt
  • 250 g Buttermilk
  • 113 g Butter (1 stick - I've used salted butter)

Instructions 

  • Preheat your oven to 220C (430F) and place the stick of butter into a square baking dish or cake pan. Place the dish into the oven so that the butter melts. While the butter is melting, make your dough.
  • In a large mixing bowl, add the all purpose flour, sugar, salt, baking powder and baking soda. Mix together until well combined.
  • Make a well in the centre of the dry flour mix and pour in the buttermilk and the sourdough starter. Use a spatula to gently bring the wet and dry ingredients into a wet dough. It will be quite marshmallowy and kind of like a big bowl of airy sourdough starter. Leave the batter to sit until the butter has melted in your dish.
  • Once the butter has fully melted, remove the pan from the oven and carefully pour in the biscuit batter. Use a spatula to smooth it out as best you can, but it will naturally level out in the oven anyway. The batter is literally swimming in butter - don't stress, the butter will absorb into the batter as it bakes. Trust the process!
  • Spray both sides of a dough scraper with oil and divide the dough into 9 even pieces. The batter will kind of fill in the lines, but this is ok.
  • Place the baking dish of sourdough butter swim biscuits into the oven for around 25 minutes or until they are golden brown and risen.
  • Remove the golden brown sourdough butter swim biscuits from the oven and allow to sit for 10 minutes so that any remaining butter can be absorbed. Use a knife to cut along the marked lines to form 9 biscuits and enjoy!

Notes

Baking Dish - I have tested this recipe a number of times and found that I prefer baking it in a 9" x 9" cake pan. I also baked it in my 9" x 11" Emile Henry Baking Dish and while they tasted amazing, they were odd shaped. I find they work better in a completely square baking dish or cake pan. Obviously this is personal preference so go by what you prefer.
 
Butter - I've used salted butter because I don't like unsalted. I have also added 10g of salt to the batter. If you don't like a lot of salt, consider using unsalted butter and halving the salt, but I find they are a bit flavorless with less salt. Again, this is personal preference.
 
Dividing the Dough - you do not have to do this step. You can simply cut the biscuits once they come out of the oven. It won't make too much difference.
 
Buttermilk - I have used buttermilk from making homemade butter. You can use store bought if you prefer. You can also just use whole milk. I recommend adding a splash of vinegar to your whole milk and allowing it to thicken for 5 minutes before adding to the batter.
