Wash the grapes, cut in half and core if necessary. Peel and slice the kiwi fruit. Heat the cream in a saucepan, but do not let it boil. Crumble the Roquefort and let it slowly melt in the cream. Let the sauce cool down while stirring occasionally.
Pour the sauce onto 4 dessert plates as a mirror, cover with the grapes and kiwis and serve chilled. A great combination of flavors!
