The key here is that pineapple and ham is a lousy pizza combination. It should be pineapple and pepperoni. Add some red pepper flake and you will have gustatory Heaven.
And yes, fruit needs to be eaten warm as well as cold, and apple pie demands a slice of sharp cheddar cheese! So let it be written. So let it be done.
Pineapple and ham is fine for pizza. But you are right, pepperoni (or bacon) is better. I haven’t tried adding jalapeno to the mix – it seems so obvious to me in retrospect – but next time I’m in a pineapple mood, I’ll try it. My usual order, though, is either plain sausage, or sausage-onion-green pepper-mushroom if I’m more in a “special” pizza mood. (Most pizzerias around here have that combo or 3/4 of that combo as their “special” or “deluxe” or whtaver.) I don’t normally like pepperoni on my pizza, but I like it with pineapple.
“The City” does not “rather famously” refer to San Francisco with no other clues that is what’s being talked about. Especially when the same statement goes on to specifically mention New York.
