"Peanut and chocolate."
Translation:Kacang dan cokelat.
"kacang" is for nuts in general (all kinds of nuts and beans/ etc..)
I usually just say "kacang" when I actually mean groundnuts (peanuts, monkey nuts) ==> "kacang tanah" = groundnuts
types of 'kacang':
The last one is also called 'kacang ... ', but that has nothing to do with a nut, it's more a sort of a bean, a long bean.
Just take a look at the picture at the wikipage.
