Ingredients 

  • 4 oz unfed sourdough starter (see note)
  • 4 oz all purpose flour
  • 4 oz water (room temperature)

Instructions

  • Weigh 4 oz unfed sourdough starter into a clean container. Discard the extra starter (see note)
  • Add 4 oz all purpose flour and 4 oz water and mix until combined. Set aside at room temperature.
  • The starter is ready to use when it has doubled in volume and a small spoonful floats when dropped into a bowl of water. This generally takes 4-5 hours but the time can vary based on dough temperature and room temperature.
  • If you do not plan to bake with the starter on the day it is fed, refrigerate 3-4 hours after feeding.
  • Feed refrigerated starter weekly. If you go longer than a week without feeding, you may want to give the starter two feedings before using.
