A waffle is a type of cake, made from a batter or dough, cooked in a waffle iron, an appliance whose core consists of hinged metal plates that impress a (typically) honeycomb pattern on the cake whilst it is baked.
The Baron Klaus Wulfenbach, the greatly esteemed and well-beloved (is he still listening?) tyrant of Europa, is said by his son to have a love of waffles. As traditional waffle-making areas are outside the Wulfenbach Empire, this suggests that the Baron traveled widely in his youth.
Some Othars have been occasioned by waffles and suffered epiphany.
In this painting a disguised Klaus Wulfenbach furthering his love of waffles can be seen in the lower left-hand corner. In the upper portion just right of the center is a building that looks very much like the Haus of Waffles.
