Spotting different snacks can be a challenge sometimes. This one looked a bit weird so I thought why not try it since I like bananas anyway.
I think this is a Polish snack which I found in Oli's Foods (Walworth Road).
It looks like a piece of poop (sorry for making you throw up) but it's a banana shaped piece of chocolate. It smells of dark chocolate too.
It tastes rather sweet in texture, and also tastes like a jaffa cake. A banana jaffa cake in fact. Very tasty.
It's less than £2, and I recommend it if you like sweet chocolatey banana flavoured snacks. ^_^
