  • 1 cup flour
  • 1 cup warm water
  • 1 pkg active dry yeast

Feeding The Starter

  • 1/2 cup flour
  • 1/2 cup warm water


  • In a large bowl, add one cup of flour, one package of active dry yeast, and one cup of water.
  • Mix until completely combined. Cover it with a towel and place it in a warm spot. An oven with a light on is the perfect place to keep it warm.
  • Allow to sit for 24 hours.
  • Take it out of warm place. Remove about 1/2 cup of starter and toss it out. Re-feed starter with 1/2 cup water and 1/2 cup flour and mix thoroughly. Cover and place in warm spot.
  • Allow to sit for 24 hours (48 hours total) and now you have an active sourdough starter.
