Translating the names of certain foods

Hi everybody,
I am having a little trouble finding some things on the food database (they may not be there at all) I might be using the wrong name for these (I only know what they call them in Costa Rica) if there are any latinos out there that know the english names I would be grateful for some help!
The veggies and fruits are:
-Pejiballes (they are small orange/green balls that grom on a certain type of palm tree, there seed has a tiny, very hard coconut in the middle. These things are killer with a little bit of mayonnaise)
-Ñampi (similar to potato only purple-ish)
-Tacaco (small and green)
-Granadilla (its a fruit that is kind of hollow and has dozens of little seeds)
-Cas (Very similar to a Guayaba only its sour-ish)
-Maracuya (Used mostly for juice and sauces)
-Zapote (bright orange fruit with a tough beige-brown skin. In colonial times people women use the inside of the big shiny seeds to dye their hair a rich brown color)

Thank you sooooooo much for any help you can give me!!!! :flowerforyou: :flowerforyou: :flowerforyou:

yeah, only a few things came up but not much info...some things, like the pejiballes, have different names in several countries. I remember hearing a panamanian that stayed with us for some time refer to them as Pifas or something like that...so these might just be the costarrican names. ill keep trying though, thanx

Hmm...not sure, havent seen passion fruit before or tried it either...another one for google.:laugh: Thanx :flowerforyou:
