When I follow a recipe, I measure everything.  My wife can eyeball her measurements from dusk till dawn and everything will still taste delicious; but my skills are not that advanced.  Regardless, if you're baking several dozen Christmas cookies, and want to make sure they all taste equally delicious (which you do, of course), try this trick...

It's a classic case of taking one thing an finding a new use for it.  In this instance, a large weekly pill case becomes a perfect container for pre-measured dry ingredients!
