Herb Preservation Practices and Common Misconceptions
Freezing herbs like rosemary is a common practice among home gardeners and cooks seeking to preserve fresh herbs. Typically, herbs are either dried or frozen after proper preparation, such as washing, chopping, and sometimes blanching. However, many amateurs may be unaware of the nuances involved, such as the importance of using airtight containers or the potential for ice crystal formation to damage cellular structure.
