Measure the milk into a jug then pour it into a saucepan leaving 100ml milk in the jug. Add the cornflour to the jug and stir to make a smooth paste.
Heat the milk in the saucepan over a medium heat. Just before the milk boils, remove the pan from the heat and stir half into the prepared cornflour mixture. Immediately pour everything back into the pan.
Cook over a medium heat, stirring as the milk bubbles and thickens into a smooth, light sauce.
Remove the pan from the heat, add the grated cheese, season with salt and pepper, and stir to combine.
Put the cooked spinach into a mixing bowl. Add the ricotta, parmesan and nutmeg, season with salt and pepper and stir to combine.
