Panko stays crispier than regular breadcrumbs both in the pantry and after cooking because of how it is made: baked with electrical current rather than conventional heat, creating a lighter, airier crumb structure that resists moisture.
How to Store Panko Breadcrumbs
Store in a cool, dry place in an airtight container. Once the original bag is opened, transfer to a sealed container to prevent moisture absorption and staling. Panko stays crisp longer than standard breadcrumbs due to its low moisture content.
