I Don't think this applies to modeling, more to eating, but being a Native of Lancaster County and consumed Scrapple I have never heard of a scrapple sandwich, at home we put pancake syrup on it before eating it an down in Philly they put Ketchup on it, as for using it for modeling, after a day or two exposed to the air it would be difficult to get close to it to see the detail work. Best regards to all you scrapple lovers.
