When embarking on the delightful journey of sourdough baking, one might ponder: Should I cover my sourdough starter? This question, seemingly straightforward, invites a myriad of considerations. Is it essential to shield the starter from dust and potential contaminants that might inhabit the air, or could such coverage inhibit its natural interaction with wild yeasts and bacteria? Furthermore, the implications of temperature variations loom large in this discourse. Could an unprotected starter suffer from excessive heat or cold, adversely affecting its fermentation process? One must also contemplate the materials used for covering. Are breathable options, like a cloth, preferable for allowing airflow, or might a tight lid foster an environment of stagnation? As one deliberates, the very essence of nurturing this living culture could hinge upon this critical decision. What nuances of your specific environment might influence the optimal approach towards covering your sourdough starter?
