Grits are a popular Southern dish made from ground corn, specifically hominy corn that has been treated with an alkali in a process called nixtamalization. They are typically cooked by boiling in water or milk until they reach a creamy consistency. Grits can be served as a side dish or a base for various toppings, such as cheese, butter, or shrimp. There are two main types of grits: white grits and yellow grits, which differ in the type of corn used. Grits are often enjoyed for breakfast but can also be served at lunch or dinner, making them a versatile staple in Southern cuisine.
