The best way to clean out your spice grinder is with a piece of white bread right? Well why waste the opportunity to make great breadcrumbs!
You can use the breadcrumbs with dinner that night or save them for later by freezing them in an airtight container! This could work with either sweet or savory dishes!
***Note: While spice grinders and coffee grinders are the same thing, they should not be USED for the same thing! While an espresso rubbed flank steak may be delicious, I don't think anyone wants rosemary-garlic coffee!
