Stop by the Souvenir Shoppe. Take a look at the little “YellowCakes” with frosting on them. Two sponge cakes for $5. There are Skull & Crossbone danger symbols on the top, written in black licorice.
In Japan, it would be about $5 (Y500) each. And they would taste incredible, because the Japanese learned how to make sponge cake from the Portuguese in the 1500s, and kept making it long after the Portuguese stopped, and then forgot how. In Japan they are called kasutera, which is a Japanization of the Portuguese "castella."
