In this article, we will explore the various methods of preserving lemongrass, their advantages, and disadvantages, and provide tips on how to choose the best method for your needs.
Why Preserve Lemongrass?
Before we dive into the preservation methods, it’s essential to understand why preserving lemongrass is necessary. Lemongrass is a tropical herb that grows in warm and humid climates. When harvested, it is highly perishable and can lose its flavor and aroma quickly due to:

Preserving lemongrass helps to slow down these processes, allowing you to enjoy its flavor and aroma for a longer period.
