To test if your starter is good, you can conduct a simple float test. Take a small spoonful of your starter and gently drop it into a glass of water. If it's active and ready for baking, the starter will float. This indicates it has enough air bubbles and fermentation activity. If it sinks, it might need more feeding time or isn't active enough for baking. Remember, the float test is just one indicator; also, consider the starter’s appearance and smell – it should be bubbly and have a pleasant, slightly tangy aroma.

FAQs & Answers

  1. What does it mean if my sourdough starter sinks in water? If your starter sinks, it typically means it is not yet active enough or hasn't developed enough fermentation bubbles to rise. It may need more feeding and time to become ready for baking.
  2. How often should I feed my sourdough starter to keep it active? Generally, feeding your starter once every 12 to 24 hours is recommended, depending on room temperature and usage frequency, to maintain its activity and fermentation strength.
  3. Can I rely solely on the float test to know if my starter is ready? The float test is a helpful indicator, but also consider the starter's bubbles, texture, and pleasant tangy aroma to determine if it is healthy and ready for baking.
