D.O. Real chocolate cake is made with real chocolate. Don't try to substitute carob. I can always tell the difference.
Carob tastes muddy.
Fresh squeezed lemonade has pulp and lacks the chemical aftertaste of a powdered lemon drink. Don't even think of serving me that fake stuff. Margarine may look like butter, but lacks the sweet savor of a real dairy product. Not only don't they look like, crunch like, or taste like real potato chips, but they can also give you gastrointestinal distress. Often, we are told they are healthier, followed by the propaganda that they are not only healthier, but taste better.
