Well, now. Maple is actually a really good smokin' wood. Take it off my land and get it in my wood pile.
Well seasoned maple compliments cherry, works well with mesquite and tempers hickory. I seldom use maple alone but when I do I am not disappointed.
As for maple bacon, that bacon is maple cured with maple syrup and then smoked with whatever wood.
Unfortunately the cheaper brands of maple bacon depend on chemicals for flavor. I have a couple of recipes for real old fashioned maple cured hams and bacons which I will some day try. For the moment the recipes are from an individual who would rather not have them published. We'll se how that goes.
But here in Vermont the maple thing is a big thing!
