Waffle, also known as Waffle, Plaid Cake, Plaid Cake and Embossed Egg Cake, is a kind of scone, which originated in Belgium and is made by an oven with a special baking tray. The upper and lower sides of the baking tray are lattice-shaped, one concave and one convex, and the poured batter is pressed out of the lattice. Waffle ovens generally have round and square baking trays, as well as hearts. However, regardless of the shape of the baking tray, the grids in the baking tray are generally rhombic or square, which is also called waffle. People in western countries often eat waffles with strawberry jam, chocolate, sugar, honey or cream, which can be used as snacks or as breakfast.
