To make the puree, pop all the ingredients in a pan, season, and reduce until almost all the liquid has gone and blitz to a smooth puree.
For the ricotta sauce, add the oil to the ricotta and season well.
Toast the pumpkin seeds with the soy sauce until beginning to colour and pop, and set to one side to go on the pizza after it comes out of Roccbox.
Put all the roasted pumpkin ingredients in a tray, season and cover with tin foil. Turn the flame down to low on Roccbox and roast for 8-10 minutes rotating halfway through.
Now (finally!) it’s time to build your pizza! Open the dough ball into a skin, top with the ricotta sauce and slop about the pumpkin puree before adding the N’Duja, roasted pumpkin and mozzarella.
Cook the pizza and top with the toasted seeds as soon as it comes out of Roccbox.
