Basics: Sourdough Starter

Ingredients Link to heading

  • Flour (any type)
  • Water (tap is fine)

Equipment Link to heading

  • Jar (to store it in)
  • Spoon (to handle the flour and water)
  • Scale (to measure your ingredients precisely)

Recipe Link to heading

  • Day 1: mix 25g of flour with 20g of water and store in the jar.
  • Day 2: feed it with 25g of flour and 20g of water, mix well.
  • Day 3 onward: repeat Day 2.
  • Feed it 24 hours, and again 4-12 hours, before usage.
  • Use it when it’s bubbly, with a 1.5x - 2x volume rise since you last fed it, and smells sour (duh!).

Notes Link to heading

  • Equal parts flour and water means 100% hidration, 25 to 20 means 80% hidration.
  • Don’t try to eyeball the measurements, use a scale!
  • The type of flour you use does not matter.
  • Feed your starter every 2-3 days at room temperature, or put it in the fridge and feed it every 1-2 weeks, maybe even less.
