I like a fair few of Green & Black's chocolate bars, and also like Nutella (as you might have guessed), so recently given the opportunity, this being on sale (it's much more expensive than Nutella, but worth it), I decided to try it finally. Comparing the ingredients, Green & Black's uses sunflower instead of palm oil, and palm fat and soy powder instead of whey powder; otherwise they are the same (the actual percentages could be different, certainly, and only Green & Black's states that the hazelnut content is 10%).
How did it taste? Which do I prefer? Well, no clear winner, though I do like the Green & Black's very much, the hazelnuts taste as if they might have been toasted, and the hazelnut taste is definitely there, strong and good. Given that the Green & Black's is much more expensive, I don't think I will be buying it as often as Nutella, but now that I know how it tastes, I definitely will be purchasing it when it's on sale.
