Umm, Maple syrup.. ....Pretty much hate the stuff, prefer fake made with sugar, some corn syrup and maple flavor.
Just a goofy personal preference.
But, as for the price. $30 per quart would be cheap considering the work, time and energy(heat) required to collect, boil down, and bottle the "liquid gold", As Nancy said it takes a lot of sap to make syrup depending on the sugar content of the sap running in any given season.
I had a friend up north that did it as a labor of love and I used to help him once in a while. His was as good as it gets, too. Just not my thing, I guess. He always gave me a couple of quarts of the stuff which I promptly gave away to those more gourmet than myself. My in laws and my business partner, namely.
This is just one of those things along with steak that I don't waste my money or time on. Now there are a few things that I will and do. Fresh seafood, biscuits and gravy, grits, fresh aspargas, wild blackberries(boy do I have a yard full of those) and wild blueberries or strawberries.
