My wife's friend from Maine sent us a big care package of some locally made syrups, sauces and stuff of that sort (like scone mix).
Anyway, among the stuff sent to us was a "Maple Chipotle Grille Sauce" from Stonewall Kitchens. I decided to try it on the bun with some coleslaw and hot sauce for my pulled pork sandwich and it was pretty damned good. Not sure how readily available this stuff is, but it is delicious. Might need to get a friend in Maine tho... lol
