I was right!
Taylor originally called his product "Taylor's Prepared Ham", but was forced to change the name after it failed to meet the new legal definition of "ham" established by the Pure Food Act of 1906.[Marketed as both "Taylor's Pork Roll" and "Trenton Pork Roll", it saw competition from products with similar names like "Rolled Pork" and "Trenton style Pork Roll". When their makers were sued by Taylor a 1910 legal case ruled that the words "Pork Roll" could not be trademarked.
In the 1910 lawsuit, it was described as "a food article made of pork, packed in a cylindrical cotton sack or bag in such form that it could be quickly prepared for cooking by slicing without removal from the bag."[ Larry Olmsted of USA Today has described the taste of the meat as "a cross between Canadian Bacon and bacon, less hammy and smoky than Canadian, fattier and saltier than bacon, with a unique texture, both crispy and slightly mushy."
