The famous Norwegian brown cheese.So what exactly is brown cheese? It's quite unusual. Visitors often say that it tastes like a sweet-savoury, fudgey Caramac, which may sound unpromising.Its described as a deeply savoury dulce de leche, and as such it can be a challenge to non-Norwegians. The sweetness comes from overcooking whey until a Maillard reaction kicks in and the milk sugars caramelise. Brown cheese doesn't go through any maturation process, and it keeps in the fridge for a few months. Suffice it to say, this is the Norwegian version of Marmite: you either love brown cheese or you hate it. No one has ever tried it and been indifferent to the stuff . Unfortunately we cant provide a recipe for brunost due to the complex manufacturing processes, however it can be tracked down through specialist cheese shops so seek it out and give it a try. You’ll either love it or hate it!
