Yes, methi (fenugreek) leaves can be stored pre-chopped with minimal bitterness if you blanch them briefly and then freeze them. This process deactivates enzymes that cause bitterness.
Chopping methi leaves releases enzymes that can lead to a bitter taste developing over time, especially when stored at room temperature or in the refrigerator for extended periods. To prevent this, follow these steps:
Wash the Methi: Thoroughly wash the methi leaves to remove any dirt or debris.
Chop the Methi: Chop the leaves to your desired size.
Blanch the Methi: Bring a pot of water to a boil. Add the chopped methi leaves and blanch for 1-2 minutes. This helps to deactivate the enzymes responsible for bitterness.
Shock in Cold Water: Immediately transfer the blanched methi leaves to a bowl of ice water. This stops the cooking process and helps retain the vibrant green color.
Drain Thoroughly: Drain the methi leaves very well. You can gently squeeze out excess water.
Freeze: Place the drained methi leaves in a freezer-safe bag or container. Spread them out in a thin layer to prevent clumping. Freeze for later use.
When you're ready to use the frozen methi, you can add it directly to your recipes without thawing.
To further minimize bitterness, consider adding a pinch of salt while blanching the methi leaves. Salt helps to draw out some of the bitter compounds.
