Make the caramel sauce
12 minWarm the cream in a separate container. Spread the sugar in one layer in a wide, heavy-bottomed pot and heat over medium without stirring. Once it starts to melt around the edges, swirl the pot to distribute it. When the sugar turns dark amber, remove the pot from the heat and gradually stir in the warm cream. Add the butter and salt, whisk until smooth and set aside to cool.
