  • 50 grams Unbleached All-Purpose Flour Or Bread Flour

Day 1

  • On day one take a clean bowl and place on a digital scale. Set to grams and make sure it is zeroed out.
  • Add 50 grams of flour and 50 grams of filtered water.
  • Mix well, cover with a towel and set aside for 24 hours to rest.

Day 2 and 3

  • After 24 hours, remove half of the starter, leaving about 50 grams.
  • Add 50 grams of all-purpose flour, or bread flour, and 50 grams of filter water.
  • Mix, cover and set aside.

Day 4-10

  • On days 4-10 repeat the same feeding process but twice a day. Once in the morning and once at night.
  • By day 7, the portion of the starter that is removed can be used in discard recipes.
  • By day 7-10 you should start to see some growth.
  • If it is doubling in size it may be ready to be added to bread.
  • Take a glass of water and drop in a scoop of the starter. If it floats, it is ready.
