Yes, the sapone di Marsiglia. Brilliant stuff, you can use to pre-treat stains before bunging in the machine, or simply to hand wash delicates. It’s also recommended for cleaning fridges.
the Barilla biscuit brand is Mulino Bianco.
For chocolate spread try the Novi brand. Unlike Nutella there’s no palm oil and there are actually hazelnuts in it.
If you’re in Tuscany go to a frantoio for the olive oil, although it will be €€€€. The cheaper oils in the supermarket are often a mixture of Spanish and Greek oils, although there will be more premium brands with single source Italian oils. Only get extra virgin, the other stuff is mechanically extracted.
There are loads of varieties of olives and other veg in oil, like artichokes, pepper, mushrooms, all delicious as antipasti or just as a snack.
cheeses and cold meats are better from the deli counter. Can you take them back though?
Clothing wise the cheap stuff is the same as elsewhere in Europe. For designer stuff we go to second hand vintage shops or outlets. There also used to be some previous season stuff from the markets, but now they’ve gone all touristy and sell shite, a bit like Portobello in London. For underwear I like Intimissimi, and if you want to splash out you can buy La Perla. Beautiful but costly.
i think there’s still an old fashioned perfumery in Florence, they make personalised perfumes, it wasn’t extortionate years ago but probably is now.
I’m sure there’s lots more that might appeal but as I live here it’s all normal and mundane shopping for me!
