In France, every home kitchen has a bread bag dedicated to keeping and storing bread of all shapes and sizes. Storing bread in cotton is the perfect medium between plastic, which creates too much moisture that leads to mold, and paper, which dries it out. Cotton will absorb any moisture while allowing the loaf to breathe. We recommend that you dedicate a Bread Bag to only storing bread. Let the flour from the crust build up over time on the inside of the bag, creating a protective layer that will help preserve the bread longer. Gently shake any excess crumbs from the bag before storing a new loaf.
