I had never heard the term "red gravy" before moving to PA and have a few questions. Can anyone clarify?
Does "red gravy" refer to any Italian tomato-based sauce or to a specific one? If the latter, what makes a sauce red gravy (as opposed to, say, marinara)?
For restaurants described as "red gravy restaurants", I assume it doesn't just mean that they serve red gravy, but that they serve a particular type of Italian food and/or have specific dishes on their menu?
