Cook the macaroni in a large pan of boiling salted water
for 8-10 minutes
or until just cooked. (It needs to be just undercooked as the pasta will be cooked again in the oven.) Drain
return to the pan and set aside.
Meanwhile
fry the pancetta in a medium frying pan over a gentle heat until it just starts to brown and crisp up
then add the thyme leaves and spring onions and cook for a further 3-4 minutes. Remove the pan from the heat and add its contents to the pasta.
For the sauce
put the butter
flour
nutmeg and mustard in a small pan set over a medium heat and cook until the butter has melted. Mix the milk and cream together in a jug and add a little to the flour and butter in the pan
stirring well. Keep adding the milk mixture
bit by bit
stirring well each time.
Once all the milk has been added
turn up the heat and boil for a minute or two. The sauce will thicken considerably
then remove the pan from the heat. Add two-thirds of the dolcelatte (or gorgonzola) and parmesan to the sauce while it is still hot and stir together until well combined. It may be a bit lumpy
but that is fine. Season to taste with salt and pepper.
Add the sauce to the pasta mixture and stir everything together. Spoon the mixture into a shallow casserole dish or four individual large ramekins.
Sprinkle the remaining cheese and the breadcrumbs over the top and bake in the oven for about 20-30 minutes
or until the cheese starts to bubble and the topping is golden-brown.
