A sourdough starter is simply flour + water + natural microbes that live in your kitchen environment. Over 5-7 days, these wild yeasts and bacteria will multiply, creating a living culture that will leaven your bread and give it that distinctive tangy flavor.
Use it at peak activity (around 24°C-26°C) for the best rise and flavor in your bread. Trust the process and be patient with your new flour pet!

🔧Troubleshooting
Acetone/Nail Polish Smell
Your starter is hungry! Feed it immediately and consider more frequent feedings.
Fuzzy Mold Growth
Discard and start fresh. Ensure clean utensils and proper jar hygiene.
Slow or No Rising
Be patient! Try a warmer location (24°C-27°C) or add a pinch of rye flour for extra nutrients.
