My children had apple juice as part of their lunch. I gave them each a generous cup-full in hopes of using up the last of it in the jug. I filled their cups with a bit to spare in the bottom of the jug...
You know that bit. Not enough for a full cup.
And then I left the jug on the counter.
And when I cleaned the living room (they were picnicking), I found unfinished apple juice in the bottoms of cups.
All together, I had a generous cup of probably no longer safe to drink apple juice on my hand and a great pitying not to dump it down the drain.
So, I poured it into my tea pot along with a cinnamon stick and a few cloves.
It's been simmering nicely for a while now, ever so slowly reducing and filling the kitchen with a potpourri scent!
I found a second use for the apple juice. Potpourri!
But, that's not all it's good for. Once it reduces to 1/2 a cup of concentrated spiced goodness, it became a confection, apple cider donuts!
Not bad for some humble, old, abandoned apple juice.
