Then Julie finally found Panettone in a chemist shop. So we tried that also, but it's not as nice as the Panpepato - in fact it tastes like sweet white flour bread-cake. I would need to try some more varieties.
Panettone is not a cake or sweet in the traditional sense, it is not supposed to be too sweet.
http://www.bauli.it/en/prodotti_natale.php?cat=11#16You should look for these, ignore any local brands offering "original italian recipe", they will never give you the real stuff.
Lately I am also question the goods of quality brands sold outside Italy. I try to buy stuff made of Italian brands I know and trust (at double the price), and very often I find a huge difference - they are horrible. I guess they don't use the same raw material for poorer markets.
Countless times I hear czech people praising food that for me is mediocre at best, most of the time just barely eatable - I don't care if I sound a snob. I need to visit a doctor soon, because my stomach and intestines feel like are in pieces, it started around february/march and it's getting worse every month - I wonder if food has something to do with this

But I digress

, "pane" means "bread" in italian, panettone would be something like "big soft bread". So yeah, it should be closer to bread then to cake. You wouldn't drink champagne with fruitcake, would you?
