As an european mac and cheese is already an abomination that you dont even know if people actually eat it in america or the media is playing a trick on the whole of europe.
Well the proportions of the ingredients are different and european cheese is usually made out of milk wnd not plastic. I made the huge mistake of going to an italian restaurant(had a good rating) and spent a good chunk of money on one of the worst meals i ever ate in my life. But look if you like it i have nothing against you just dont try to call it italian.
Grapes and cheese is a classic combo.
It could work, if you can balance acidity with the sweetness, and the saltyness of the sauce to the sweetness of the rasins.
