In this tasty pasta dish you add the stock gradually as the pasta cooks, just like making a risotto. This absorption method is a classic Italian way to cook pasta to give it a rich and creamy texture but without adding cream. As a bonus it is also a very adaptable recipe – try swapping the sausages for tinned tuna fish, or use sweetcorn in place of the peas, or spice it up with a few dried chilli flakes.
