Scalloping in terms of cooking refers to the constitution of a dish. A scalloped food is baked in a cheese or cream sauce, or a combination of both. Both cooking methods are commonly used for potatoes. However, corn can also be scalloped. Scalloped most often refers to thinly sliced foods that are baked in sauce. The most common example is scalloped potatoes. Hence, corn is not sliced, so scalloped corn is a deviation from the traditional meaning, which is derived from a word that literally means sliced.
