To store banana stem (vazhai thandu), chop it into small pieces, soak them in diluted buttermilk or water with lemon juice to prevent discoloration, and refrigerate in an airtight container for up to 2-3 days.
Banana stem, also known as vazhai thandu, tends to discolor quickly due to oxidation. Proper storage is crucial to maintain its freshness and prevent it from becoming unappetizing. Here's a step-by-step guide:
Preparation: Begin by thoroughly cleaning the banana stem. Remove the outer layers until you reach the tender, edible core.
Chopping: Chop the stem into small, manageable pieces. The size depends on your intended use, but smaller pieces are generally easier to store and cook.
Soaking: Immediately after chopping, soak the pieces in diluted buttermilk or water mixed with lemon juice (about 1 tablespoon of lemon juice per cup of water). This helps prevent oxidation and keeps the stem from turning brown.
Storage: Transfer the soaked banana stem pieces to an airtight container. Ensure the pieces are submerged in the liquid to minimize air exposure.
Refrigeration: Store the container in the refrigerator. Properly stored banana stem can last for up to 2-3 days.
Change the soaking liquid daily to further prevent discoloration and maintain the freshness of the banana stem. This will help extend its shelf life and preserve its flavor.
