You can substitute 100g crumbled blue cheese for the gruyère, or add 310g can drained corn kernels for a delicious corn-flavoured potato puff. You can also use nicola or pink-eye potatoes for this recipe. Note
You can buy packaged pizza bases in two sizes: the large ones we’ve used here measure 25cm across; smaller ones measure 15cm across and come packaged in pairs with a total weight of 225g. Use six of the small ones to make individual pizzettas. Note
