Well, I can't make it a "once a year treat" until I use up the bottle, but I will try to find a better use for the remainder. Get thee behind me, maple syrup!
I eat junk food once in a blue moon, so I carefully scrutinized every box of "good" waffles in the freezer case, but in the end, my mouth won over my good sense, and I bought the Eggos anyway. (Savoring every bite.)
But that's not why I'm posting right now. (It is impossible for me to make a post without a digression of some kind, and I'm even worse in person.) I wanted to add this link, which has a ton of information about maple syrup:

The George Mateljan Foundation is my favorite site for in-depth information about specific foods.
