  • Make sure to mix this well. You want the sourdough starter to be well combined with the other wet ingredients.
  • Add the wet ingredients to the dry ingredients and mix until well combined and no dry spots are left, scraping the sides of the bowl as you go. Make sure to not overmix as this will leave you with tough cake.
