Personally, Taylor pork roll never did much for me. I'd take it out of the sandwich and just let the grease add flavor to the egg and cheese. Its too processed for my taste. But very popular in some places. We can get it relatively easily in Los Angeles but I prefer to point to it and simply marvel at its availability rather than actually buy any and eat it.
Now fried bologna... that's different. Yummy!
Have you seen this... if you are thinking about making some yourself:
As a fellow Bostonian (with heritage dating back to the 1600's) I would have assumed that too. But you know those wild and crazy New Jersey folks... Taylor ham should really be known as Taylor "ham", but it isn't. And they aren't about to change things because we don't understand. Ha ha ha. AKA pork roll... which is much more descriptive.
