Half Gruyère cheese, half Vacherin – that’s how you make a Fribourg fondue, Switzerland's favourite. Exactly why this warm "cheese soup" became our national dish is unclear. Perhaps it is down to symbolism: just as the country comprises four languages and cultures, a fondue also brings together various elements that make a greater whole. A fondue is shared democratically, and enjoyed with (plenty of) drink, laughter and chat.
