Turtle soup and/or other odd and/or frightful things common in romance novels

Today I learned that "turtle soup" was actually made from turtles. I'd assumed that it was just a name and it didn't really include actual turtles. But then tonight I googled it and learned the truth.

... I don't know that I can read about sumptuous dinners in novels set in Regency and Victorian England now without being revolted.
