I bake my own wheat loaves and rolls, and either bake a size or quantity I know we will eat before it becomes stale, or halve the portion of risen dough, putting half into the freezer.
Any bread that is left over, I cut into croutons and dry. Usually, once they are dry, I put them through an old-fashioned manual mincer to make breadcrumbs, but I do sometimes serve croutons with soup. Dried bread that has been soak in water, and had crusts removed can be used for thickening soup, so sometimes I use my supply of this, too.
We buy rye bread in small packets that we know we will use up while it is still fresh.
Both wheat loaves, rolls and breadcrumbs are much too expensive here for me to want to buy them. And of course, shop-bought bread from the supermarkets is factory made and fairly tasteless. Bread bought in a bakery is so expensive that I wonder who on earth can afford it on a regular basis.
