Pasta with Cheese

My kids just love anything that looks quite white and simple, so this is a very basic recipe that you can build on, even adding some cooked peas or zucchini (courgettes). You can add any cheese you like to the basic ricotta mixture: mascarpone, mozzarella, pecorino, parmesan... Adults might like some gorgonzola or similar added to theirs. My friend Caterina used a mature pecorino, which was stunning.
