So, a Greek guy in Canada made an Italian staple into something that he thought would represent a Hawaiian cuisine (even though it was just the can, many people naively believe it truly is a Hawaiian dish)
Once someone told me they thought that’s how they ate their pizza over there. Lol.
Nevertheless, if I were in Canada at that time, I would have visited his restaurant and ordered one of the originals. It’s not the best pizza topping but it is also not the worst. (I hate anchovies, fish of any kind or mushrooms on my pizza. Mushrooms are good in other dishes.)
For what it’s worth I believe that mushroom should be sliced thin and thoroughly sauteed before they’re put on the pie. They should have a density somewhere around sausage and really shouldn’t change the texture of the cheese much if they’re done right.
I know a lot of places that just throw raw sliced mushrooms on a pizza and I think that’s horrible.
And trovise on the other hand should just be salty with a slight umami flavor. I think the only true consistency problem I see with them is if you get a whole anchovy in your mouth right along your molars, when you bite into it they will be a bit chewy which is not great. Realistically nothing on a pizza should be chewy ;)
