Guylian artisanal truffles are marbled with 100% pure, silky smooth milk, dark & white Belgian chocolate. Each truffle is then filled with our Signature Hazelnut Filling; the original recipe of Guy & Liliane. We start by slow roasting and caramelizing fresh Mediterranean hazelnuts in small-batch copper kettles and then finely crushing and blending them with luxuriously rich & creamy Belgian milk chocolate. This signature recipe is made exclusively by Guylian's master chocolatiers in Sint-Niklaas, Belgium.
