Another winter occupation for ice cream sellers seems to have been selling hot chestnuts. So many of the Italian immigrants were connected with food in some way, often at the rather more luxurious end of the market.
I wonder when the pizza invasion began?

Just found this on Wikepedia, which I think must refer to the Edinburgh Crollas:
Most expensive pizza created was made by the restaurateur Domenico
Crolla who created a £2,000 priced Valentine pizza which included toppings such as sunblush-tomato sauce, Scottish smoked salmon, medallions of venison, edible gold, lobster marinated in the finest cognac and champagne-soaked caviar.
Ugh! Sounds disgusting! I'd much rather have an ice cream or a bag of hot chestnuts.
