Do you save the salt from the pretzel bag? How about the sugar from a package of candied ginger? Cookie crumbs? Bread crumbs? Those things add up faster than you might think if you have a special place to put them. And USE them. There's no sense in keeping dibs and dabs if you don't use them.
The last package of candied ginger I used yielded enough sugar to sweeten a cup of tea. Why not? I paid for it.
