Say cheeeese
Cheddar is nice, also on a tasty burger, but when it comes to swiss, french and corse cheese..
I cannot pick one, there are a lot of excellent ones. Appenzeller is very good, as is old ripe Gouda 'Amsterdam' type, or Tête de Moines. And all those camemberts, and goat cheese..
And then, there is "Harzer Käse"
