Anyone who is familiar with the Sausage Maker and their catalog knows about a product they sell called Fermento. It creates the tartness in home made beef or venison sticks which makes the flavor similar to a Slim Jim. So call me cheap or an overly frugal Yankee but I really have a hard time having to pay 3 dollars handling charge then a 15 dollar shipping charge for a product that only cost 12 dollars and change to begin with! Does anyone of you know of a decent substitute for this product, something that maybe can be purchased in a local market or the paint dept. of the local neighborhood hardware store or someplace like that? ;-)
