Equipment

  • 1 Glass Container or Wide Mouth Mason
  • 1 Wooden Spoon or Spatula
  • ¼ Measuring Cup
  • 1 cup Measuring Cup
  • 1 Tea Towel To Cover Container
  • 1 Rubber band or String

Materials

  • ¼ cup Cane Sugar Unbleached
  • ¼ cup Potato Flakes Organic
  • 1 cup Bread Flour Unbleached Red Wheat Flour
  • 1 cup Warm or Room Temp Water Filtered Water

Instructions

  • Measure 1 cup bread flour, ¼ cup potato flakes, ¼ cup cane sugar, and 1 cup warm water.
    Add these ingredients directly into your existing starter container — I personally do not discard any old starter.
    If you’re using a smaller jar, make sure to leave plenty of room for expansion.
    I personally use a large glass container with a loose-fitting lid, which gives my starter space to rise and breathe.
    Stir gently with a wooden spoon or spatula until everything is well combined.
    Cover loosely with a tea towel or a non-airtight lid to allow airflow.
    Leave your starter at room temperature for 6–8 hours, or until bubbly, active, and slightly risen.
    Once it’s lively and ready, make dough recipe and then store it in the refrigerator until the next feeding or bake.

Notes

  • Feed your starter every 5–8 days if not baking regularly.
  • Always allow room in the jar — this starter loves to rise!
  • For best flavor, use organic ingredients and filtered water.
  • As your starter ages, it develops a deeper, more complex tang.
