Equipment

Ingredients

  • 50 g active sourdough starter
  • 50 g bread flour unbleached
  • 50 g filtered water

Instructions

Discard

  • Weigh the jar with the starter in it and discard down to 50 g. Save the discard in a separate jar in the fridge if you want to use it.

Feed

  • Add 50 g bread flour and 50 g filtered water. Stir until no dry flour remains and scrape down the sides.
  • Mark the level with a rubber band and rest the lid on loosely.

Rise

  • Leave in a warm spot for 4-8 hours, until the starter has doubled and the domed surface just begins to flatten. That is peak.

Use or store

  • Use it at peak, feed again, or refrigerate it until the next weekly feed.

Notes

  • Feeding schedule: once a day on the counter, twice a day at 78°F and above, once a week in the fridge.
  • Ratios: 1:1:1 standard, 1:2:2 for a longer gap, 1:5:5 overnight. The first number is starter, then flour, then water, all by weight.
  • To wake a fridge starter for baking, feed twice at 1:1:1, 8-12 hours apart, starting the day before you bake.
  • Keep a 20 g starter fed at 1:1:1 for much less discard.
  • Dark liquid on top means hungry, not spoiled. Fuzzy growth or pink or orange color means start over.
