Question: are buttercup and kabocha squash the same?
Answer: Buttercup squash is a lot like kabocha with a belly button — but generally a little larger, a little moister, and not as nuanced in terms of flavor. Kabocha is round with no imperfections on button, the area where the turban grows on a Buttercup. ... The kabocha stem shape is different as well, not squishy.
