Kolhrab Again...

Since I discovered what Kohlrabi was, and since I discovered that I can use it to make Som Tom, I was as pleased as ever to receive it again in my veggie box delivery this week.

The recipe using Kohlrabi can be found on a previous post here. Today I thought I would play around with my camera, and voila, I think my photo turned out not bad thank you very much. BUT I realised that I had forgotten a vital ingredient :( Can you guess what it is?
