By subjecting the leaves to high heat for a brief period, blanching helps to halt the enzymatic processes that can cause flavor deterioration over time. As a result, the frozen sorrel leaves retain their distinct tangy and lemony taste.
- Preserving Texture: Blanching also helps to partially cook the sorrel leaves, which is beneficial for preserving their texture. The brief exposure to hot water softens the leaves slightly, making them more pliable and less likely to become tough and fibrous during freezing. This ensures that the frozen leaves remain tender and easy to work with in your recipes.
- Eliminating Microorganisms: Blanching serves as an additional measure to reduce the presence of harmful microorganisms on the surface of the sorrel leaves. Although washing the leaves helps, blanching provides an extra level of safety by subjecting the leaves to high temperatures, which can help eliminate potential pathogens.
The blanching process is relatively quick and simple. To blanch sorrel leaves, bring a pot of water to a rolling boil. Meanwhile, prepare a separate bowl filled with ice-cold water. Submerge the sorrel leaves in the boiling water for approximately 10 to 15 seconds – this short duration is sufficient to achieve the desired blanching effect without overcooking the leaves.
Immediately after blanching, transfer the sorrel leaves into the ice water bath. This rapid cooling process, known as “shocking,” halts the cooking process and helps maintain the leaves’ color, flavor, and texture. Once the leaves are completely cooled, remove them from the ice water bath and pat them dry before proceeding to the next steps of arranging and packaging for freezing.
