Dark chocolate salted caramel fondue

Method

1. Put the sugar in a pan with 4 tbsp water and heat gently until dissolved. Bubble until the mixture turns a deep caramel colour, then quickly whisk in the salted butter and chopped dark chocolate until melted and smooth (be careful as it might spit).
2. Whisk in the double cream to make a smooth, glossy sauce. Once cooled slightly, add a pinch of salt, then serve with marshmallows (vegetarian if need be), biscotti and fresh fruit to dip.
