How can I properly freeze jalapenos to preserve their freshness and flavor for future use?

To properly freeze jalapenos for future use, start by washing and drying them thoroughly. Remove the stems and seeds, then slice or chop them as desired. Place the jalapenos in a single layer on a baking sheet and freeze until solid. Transfer the frozen jalapenos to a freezer-safe bag or container, removing as much air as possible before sealing. Label the container with the date and store in the freezer for up to 6 months. Thaw before using in recipes for best results.
