alright, i know a lot of people arent going to know about a passion fruit since they are really uncommon, so ill answer the question in advance
first off ive never had a passion fruit that looked like the one pictured above, so there might be different kinds, but the ones ive had are perfectly round and a lttle bit smaller than a baseball. the skin on the passionfruit is a harder, durable one...so much so that you almost have to use a knife to cut them open. the look of the insides of them leaves much to be desired. it really just looks like someone that was sick just blew their nose it (sorry..its the most accurate decription
). its filled with a gree-yellow colored fruit thats kinda formless...in between liquid and solid. the taste is very unique- tangy yet sweet, but not tasting like any other fruit. very tropical.
overall im voting for the kiwi fruit. the taste of passionfruit is good, but its hard for me to get over how nasty they look inside and usually i cant even finish one before i start getting grossed out.
