To make fresh breadcrumbs, tear the bread into pieces and drop into a food processor fitted with a blade attachment. Pulse until you have breadcrumbs of the size you want. If you want to make very even breadcrumbs, push them through a coarse sieve. Will keep in an airtight container at room temperature for up to a week.

To make dried breadcrumbs, tear the bread into pieces and bake in a low oven until the pieces are completely dried out. Pulse in a food processor as before. Will keep chilled for up to two months, or frozen for six months.
