Grate Gouda roughly and arrange on a plate with Parmesan and Raclette cheese. Put the noodles in plenty of boiling salted water and cook for about 9 minutes.
Stir the crème fraîche until smooth and place in a bowl. Divide the remaining ingredients into small bowls as well. Pour the noodles onto a sieve, rinse with cold water and drain. Also put them into a bowl and keep warm on the raclette machine if necessary. Add spices and herbs, e.g. salt, pepper, paprika powder and thyme, or some chilli sauce for the bean pan to the raclette.
