But it's never as thick as depicted in anime, is it just thick in anime b/c its easier to draw that way or is it supposed to be that thick? P.s Is Japanese curry sweet or spicy?

Please do NOT answer if you dont know, I really dont want someone saying " maybe" or "idk" in their answer. Also don't tell me to look it up b/c I have tried, that's why Im using yahoo.answers to find out.
