A sourdough starter is a culture of natural bacteria and yeast that is used to leaven bread.You only need flour and water to make your own starter from scratch!
Use a clean, glass jar with a wide opening to make stirring with a small spatula easy.A baking scale will ensure your ingredients are measured properly.
For best results, keep your starter in a warm location like a bread proofer or an oven with the light turned on.Sourdough yeasts thrive in warm (not hot) conditions.
