I recently saw a commercial in which Ragu and Prego were compared in a taste test. I think Prego won, even among regular Ragu-ers.
In other words, among people with lousy taste in spaghetti sauce, when choosing between two mediocre sauces, one of them did, in fact, have to win.
And then there was the Chef Boyar-dee commercial, in which we were told the history of this American staple, how a restaurant's pasta sauce became so popular that people were asking for the recipe and instead, they started sending it home with them.
In other words, back in the 1920s, Americans had no idea how to make a decent pasta sauce.
