Dynamic contrast refers to foods that generate contrast sensation in our mouths. For example, chocolate candies with hard sweet chocolate shells and smooth melting sour centres. We really enjoy foods, which give us one kind of texture and taste, and later the other ones. Maybe something soft to start with, then something chewy, and so on. These foods are more appealing, because we don’t want to stimulate the same senses repeatedly, and want to experience as many different stimuli as possible with one bite.
