Proper Storage Methods

To get the longest usable life out of your squash blossoms, it’s important to store them properly. Here are some tips:

Refrigerate promptly – After harvesting or purchasing squash blossoms, make sure to refrigerate them as soon as possible. Leaving them at room temperature will drastically decrease their shelf life.

Line container with paper towels – Line the storage container with paper towels or a clean kitchen towel. This absorbs excess moisture and keeps the blossoms dry.

Store loosely – Do not pack the blossoms tightly together. Give them space to “breathe” so air can circulate and prevent mold growth.

Use breathable container – A plastic bag with holes poked in it or a plastic container with a lid allows for some air flow. An airtight container traps moisture.

Rinse gently – A quick gentle rinse removes dirt and debris. Pat dry thoroughly with paper towels before refrigerating.

Keep refrigerated – Consistent refrigeration between 32-40°F maintains freshness and slows deterioration.
