I finally had to cut open that round papaya in the fridge.
Lesson learnt : Put papaya in the fridge after it has been left outside for awhile to ripen. If not, according to my dad, the fruit would not have a chance to mature naturally, its growth somewhat stunted.
To be honest, I'm not sure if this exotic fruit would eventually taste like those back home, but having a taste of something so familiar really made me happy! Looking at this papaya reminds me of sweet little blessings ^.^
