Tried our hand at making deep dish pizza for new years. Turned out quite good but I’m no expert so I can’t say how accurate it was. I am told the toppings are supposed to all go under the sauce but I couldn’t resist putting some pepperoni on top
No judgement but here in the UK this is more like what we’d call a flan than a pizza or a pie. So instead of arguing about pizzas and pies, why not embrace a third category?
You can call anything a pizza if you want. It becomes a useful term if it’s commonly understood by your audience.
