If I remember her line correctly here she can’t decide which is the desert, and which is the appetizer. it can henceforth be noted that ponies consider meat to be on par to icecream, or cake in our society. it makes sense really if you consider that most of our desserts won’t kill us except in large amounts, and meat won’t kill a horse instantly either. they are both things not required for survival by each species in question, so that’s another parallel. therefore meat = icecream
