Yes, refrigerating flour during the monsoon season can help prevent clumping by keeping it dry and at a consistent temperature, thus inhibiting moisture absorption.
During the monsoon season, humidity levels are significantly higher, which can cause flour to absorb moisture from the air. This absorbed moisture leads to clumping and can even promote the growth of mold or bacteria, shortening the flour's shelf life. Refrigeration provides a cool, relatively dry environment that minimizes moisture absorption. To refrigerate flour effectively, store it in an airtight container or a resealable plastic bag. Before using refrigerated flour, allow it to come to room temperature to prevent condensation from forming when it's exposed to warmer air. This helps maintain the flour's texture and baking properties.
If you don't have space in your refrigerator, consider storing flour in an airtight container with a desiccant packet (like silica gel) to absorb moisture. Replace the desiccant packet regularly to maintain its effectiveness.
