Potato wedges are wedges of potatoes, often large and unpeeled, that are either baked or fried. They are sold at diners and fast food restaurants. In Australia, potato wedges are a common bar food, that are almost always served with sour cream and sweet chilli sauce. They are usually seasoned with a variety of spices, commonly paprika, salt and pepper.
When compared to steak-cut chips (UK), fries (US and global), roasted potatoes or crinkle-cut chips (UK), a wedge could be defined as having distinct corners when viewed as a cross-section perpendicular to the normal- a centreline running along the length of the cut potato form. This can be viewed as a triangular section, should there be 4 corners it would commonly be referred to as just a chip/fries.
