Notes

  • Healthy sourdough starter has a sweet, yeasty smell.
  • A new starter doesn't have as much sourdough flavor as an older starter!
  • Always use a glass container with a loose fitting lid to keep your starter in.
  • Sourdough does not react well to stainless steel!
  • Sourdough tastes different in different parts of the country, based on the type of yeast in the air. If you move and take your sourdough starter with you, the flavor will change based on the airborne yeast in your new location. Crazy, right?
  • You can use sourdough starter for a variety of recipes, not just bread!
