The milk chocolate shell is sweet, creamy, and comforting — the flavour profile most people associate instinctively with chocolate. Against the pistachio kunafa filling, this creates a harmonious, rounded experience where every element enhances every other. The sweetness of the chocolate amplifies the nuttiness of the pistachio, and the kataifi crunch cuts through the creaminess with precision. This is the bar that went viral, and it went viral for good reason — it's the most immediately approachable and universally enjoyable version. If you're buying your first FIX bar, start here.

Dark chocolate introduces something the milk version doesn't have: tension. The mild bitterness of high-quality dark chocolate sits in opposition to the sweetness of the pistachio cream, creating a contrast that chocolate connoisseurs will immediately recognise as more complex and more interesting. The finish is longer, the overall experience more intense. This version particularly suits coffee pairing — a good espresso alongside a dark chocolate FIX bar is genuinely exceptional. Recommended for anyone who usually reaches for 70%+ dark chocolate over milk.

White chocolate contains no cocoa solids — only cocoa butter, milk, and sugar. This means there's nothing in the shell to compete with the pistachio flavour in the filling, which emerges more prominently and clearly than in either the milk or dark versions. The overall profile is sweeter, creamier, and more dessert-like. The pistachio note is the clearest here — almost wine-like in its expressiveness. Some find this version almost too sweet; others find it the most elegant of the three. It's the version most likely to be surprising on first encounter and most likely to become a favourite on reflection.
