Boston's famous "Boston cream pie" is actually a dessert invented by a French chef, and the beautiful icing on the surface is very delicate!Just looking at it makes me enraptured.There is also a sense of volume, and I was worried at first that it would be sweet, and I wondered if I could eat it all.Caramel whipped cream and banana custard are layered on a bittersweet chocolate-coated coffee sponge, and the sweetness is surprisingly modest.I miss the bitter sweetness of the moist sponge.
