I've been researching VPN pizzas places in my area only to find most of them have a pistachio pizza. I was ideally looking for a place like Mother Dough in Los Angeles. My problem is that my son and I are highly allergic to this nut and can't even be near it so I'm afraid we probably can't even share an oven due to possible cross contamination. I called around to all the pizza places and found this item on the menu. out of frustration I said. "when did pizza start having pistachios on them?" And I was told by one restaurant that pistachios on pizza is traditionally Italian in Italy. Really? I had no idea. I know there are pistachios in desserts but I was told in Italy, pizza is pretty basic with meat on it sometimes. is it traditional of was the person just making this up? I've never been to Italy so I can't speak to this.
