Boil the tagliatelle in salted water until al dente, as instructed on the package. Mix the cream and parmesan together. Fry the bacon, onions, and garlic in a frying pan. Pour the cream over and let it simmer lightly. Drain the pasta in a colander and add it to the pan. Mix thoroughly. Season with salt (remember that the bacon may be salty enough) and freshly ground black pepper. Fold in the Snøfrisk® and serve the dish topped with a raw egg. Guests mix the egg into their own dishes. Garnish with fresh herbs.
