couldn't eat it EVERY day. It would be nice to eat yours on the one day,
however.

Can't you find it in Italy, then? Not even as panna acida, p. acidula,
or p. con fermenti?
Or you can try and replace it with Greek yogurt (yogurt greco).

The one time I bought some horrifically expensive sour cream at Castroni in
Rome, it was baaaad. I think you have to be much farther north than Umbria
to find it freely in shops and markets.
I do use Fage Greek yogurt and it is tasty, but it is NOT creme fraiche nor
sour cream.
