> “The next day, I enjoyed pan-roasted oysters with a tomato sauce over rice, broccoli salad and bread pudding with chocolate sauce.” A comma after “broccoli salad” would have cleared the table before dessert. I think if you write a sentence that's highly dependent on the reader paying careful attention to where an easy-to-miss comma is, you assume all readers know what Oxford commas are, and the sentence generates a…
The next day I enjoyed - pan-roasted oysters with a tomato sauce over rice - boccoli salad - bread pudding with chocolate sauce. There, I fixed it.
- main-dishes (x1)
- side-dishes (x2)
The entree set has 1 item in it, the "pan-roasted oysters with a tomato sauce over rice.The ingredients of "entree" follow the same hierarchical structure as the ingredients of "meal," so: -main-ingredients (x1)
-side-ingredients (x2)
Since we're only talking about two sets here, a comma separating them is unnecessary. You could use one if you wanted, ("pan-roasted oysters, with a tomato sauce over rice") but then the syntax of the sentence would be off. You'd have a list of three things: -pan roasted oysters
-a tomato sauce over rice
-broccoli salad and bread pudding with chocolate sauce
This is logically inconsistent because the oysters, tomatoes, and rice comprise a single dish. The tomatoes and rice don't stand on their own but describe how the oysters are prepared and served, just as the non-entrees describe how the meal is served.Lets compare:
ORIGINAL: >“The next day, I enjoyed pan-roasted oysters with a tomato sauce over rice, broccoli salad and bread pudding with chocolate sauce."
OXFORD COMMA: > “The next day, I enjoyed pan-roasted oysters, with a tomato sauce over rice, broccoli salad, and bread pudding with chocolate sauce."
By structuring the sentence in that way, you erase any information about the value of the meal, and the relationships between its components. In return you ensure that someone won't think there was chocolate sauce on the broccoli salad.
