Hello... Rosa I've got some Baking Powder somewhere in the kitchen and according to Wikipedia "Most commercially-available baking powders are made up of an alkaline component (typically baking soda, also known as sodium bicarbonate), one or more acid salts, and an inert starch (cornstarch in most cases, though potato starch may also be used)."
Don't know what the equivalent is in Italy, or if indeed such a thing exists, but after lots of searching in vain in supermarkets, I bought mine from an Indian food shop here in Milan which stocks lots of English imported stuff you can't get anywhere else (Marmite, Horlicks etc!), maybe if there's somewhere like that in Venice they'll have some too...
Franca, that white chocolate cake sounds divine!
As for Taranto, yes lots of heavy industry - steelworks and a refinery both looming over the city and polluting the cr*p out of the air, soil and water with dioxins... of course Milan is polluted too but somehow it doesn't scare me as much here (perhaps it should!)
They're closing consultori in this area too, our local one is now just for vaccinations only. It was quite helpful to have one nearby when DD was born, in addition to the hospital drop-in centre, although looking back I would tone down the militant "Breastfeeding on demand" stance, I ended up creating a monster and am still trying to stop BF on demand 18 months down the line
