We also call it the heel. If my son is around he eats them.
Sometimes I save them in a plastic bag and put them in the freezer, when I have enough I make homemade stuffing. The hubby loves it with chicken.
I sometimes make bread pudding, croutons or bread crumbs.
In the winter I throw some out for the birds.
I don't know what you call them, but my dog usually gets them. We have a ritual with singing and dancing when I open a new loaf of bread. It's quite an event.
It's the heel. I used to toss those out, but my wife uses them for making meatloaf, one of my favorite dishes, so now I put them in the heel bag, good boy that I am.
I keep a small roaster pan in the oven and toss the crusts into it, then when it's full, out comes the manual hand-crank meat grinder, and I grind the crusts into crumbs which I use in the making of certain dishes.
When I was young one of my jobs (unofficially) was to take moms roaster pan full of crusts out of the oven and using the manual hand-crank meat grinder, grind the bread crusts into crumbs. Depending on how full moms roaster pan was, it used to take me an hour or more to tackle the pan, but usually rewarded mom with two ice cream pails full of bread crumbs.
For those who may not know, for a loaf of bread sitting out on the counter, keeping the crust with the loaf helps to maintain the freshness of the loaf.
Heel of course. We freeze them to be combined with cornbread to make dressing for the Holidays. Not too many of course. Have to have a lot of cornbread to a few heels.
