Never throw away your day-old bread… it makes great breadcrumbs. To make fresh breadcrumbs, remove the crusts from day-old white bread slices (sourdough and ciabatta are ideal) and cut into cubes. Transfer the cubes to the bowl of a food processor and process until crumbed. If not using straight away, transfer to a sealable plastic bag. Label, date and freeze breadcrumbs for up to 3 months. Place the frozen breadcrumbs in the fridge until thawed, as required.
