As the summer months approach, many of us look forward to enjoying fresh corn on the cob, either from our local farmer’s market or our own backyard gardens. However, when it comes to storing corn on the cob in the husk, there’s often confusion about whether it should be refrigerated or not. In this article, we’ll delve into the world of corn storage, exploring the best practices for keeping your corn fresh and delicious for a longer period.
Understanding Corn on the Cob
Before we dive into the storage aspect, it’s essential to understand the basics of corn on the cob. Corn is a warm-season crop that thrives in temperatures between 65°F and 85°F (18°C and 30°C). When harvested, corn is typically left in its husk, which helps to protect the kernels from moisture loss and other environmental factors. The husk also plays a crucial role in maintaining the corn’s natural sweetness, as it prevents the kernels from coming into contact with oxygen, which can cause the sugars to convert into starches.
The Importance of Proper Storage
