To be fair, there's like thirty different names for the same ingredients in slightly different configurations in the popular mexican foods. Even if flan and Japanese puddings are essentially the same thing, having a different name because it's in Japan wouldn't be weird in comparison to stuff like that.
If someone did that (page 3) in my house, the fire alarm would be blaring loud enough to wake the dead and we'd be getting calls from the security company asking if we need a fire engine... and we'd be like "nope, just making an omelette" =P
