Actually, there is one substitute that I use just about as often as maple syrup, Honey. Unfiltered raw honey I buy from a producer in South Dakota. He had a brother just down the road from me and we got to talking not long after I moved out here. He offered me a great deal I couldn't pass up, $20 per gallon in 5 gallon buckets. I've only bought two buckets so far, but even making Mead I still have enough left to share with neighbors, lol.
Honey on buckwheat pancakes, Awesome!!
