How do you make bread crumbs for stuffing?

Cut whatever leftover bread you are using into chunks. If you wish, you can remove the crusts, which will give you a more consistently textured crumb. (I don't bother myself - kind of hard to remove just the crust from a baguette!) Spread the chunks out on a baking tray and place in a 200°F oven for 30 minutes or until they are thoroughly dried out and turning a bit golden. Remove from the oven and allow to cool completely. Use a food processor to grind the cooled chunks into crumbs (takes about 1 minute on high and you may need to pulse it a bit to get things started). Pour the crumbs into freezer bags, date and freeze until ready to use. You can keep it in the freezer for up to three months.
