This is lime. In Indonesia we called it jeruk nipis. Lime has a strong smell. It usually been used to remove fishy smell, to cure cough, to make fresh beverages, etc. I like its smell, very refreshing. But the taste is so sour that make me frown, like this (>.<). Hehe.
I took this photo on February 7th, 2015 in Bogor when I wanted to make DIY cough elixir :)
