To prevent freezer burn when storing sabzi in boxes, ensure the sabzi is completely cooled before packing, use airtight containers or freezer bags, and remove as much air as possible before sealing.
Freezer burn occurs when moisture escapes from the food's surface and evaporates, leading to dehydration and oxidation. This results in a change in texture and flavor. To prevent this when storing sabzi:
Cool Completely: Allow the cooked sabzi to cool down completely before packing it for freezing. Warm food creates condensation inside the container, which will turn into ice crystals and contribute to freezer burn.
Choose the Right Container: Use airtight containers specifically designed for freezer storage or heavy-duty freezer bags. These containers provide a barrier against air and moisture.
Remove Excess Air: If using freezer bags, press out as much air as possible before sealing. You can use a vacuum sealer for optimal results. If using containers, ensure the lid is tightly sealed.
Portion Control: Divide the sabzi into smaller, manageable portions. This allows you to thaw only what you need, reducing the amount of time the remaining sabzi is exposed to temperature fluctuations.
Label and Date: Label each container or bag with the contents and the date of freezing. This helps you keep track of how long the sabzi has been stored and ensures you use it within a reasonable timeframe (ideally within 2-3 months for best quality).
Consider adding a thin layer of oil or ghee on top of the sabzi before freezing. This creates an extra barrier against air and helps to retain moisture, further preventing freezer burn.
