The term 'Doughnut Cousins' refers to two popular breakfast items, bagels and doughnuts. Bagels are a type of bread roll that is boiled and then baked, usually in a circular shape with a hole in the center. Doughnuts are a deep-fried pastry made from a sweet dough. Both bagels and doughnuts are often served with cream cheese, butter, or jam. They are both popular breakfast items and can be found in many bakeries and cafes.
