There is one word that I could use to describe this candy, and that's "green". I don't know if I've ever eaten a candy that tasted so green before. If I were to break down the flavour, I would say it has a slight tart flavour, like a lime, mixed with an almost grassy flavour. There's also a slight hint of spicy that sneaks up on you about halfway through the candy. I guess I could use two words to describe it then, one of the words would be “green”, the other would be “weird”.
Don't get me wrong, it's not weird as in you wouldn't want to eat it, it's more along the lines of weird like something you've never tried before. I'm not sure if I'd want to eat a whole bunch of these, but the strange experience wasn't entirely unpleasant. I think the flavour that probably threw me off the most was the slight grassy flavour. It's not something you normally expect from a sweet candy, however the more I think about it, the more I realise that this candy isn't really that sweet.
From what I've seen on the Internet, imli is tamarind. If this is in fact a tamarind candy, it's very different than the ones I've had in the past. Those have been primarily sweet. I'm wondering, because of the green package, if this is supposed to taste like an unripe tamarind. That would explain the "green" flavour, and also the green bean pod on the front of the package.
If you can get your hands on a package of these, I highly recommend trying it out. I wouldn't invest in a whole box of them, just a couple will do.
