Sounds delicious. What shape of pasta did you use?
I had a similar pasta with sundried tomato, and walnut with spinach, and it was amazing.
Originally, I came across a version of this recipe in a Nigel Slater recipe book (Real Fast Food, if memory serves), around twenty five years ago.
Anyway, I diced Gorgonzola, and Stilton, and some Birbablu, allowing them to melt in an Italian sauté pan under a low heat.
Any blue cheese will work with this - or, any blend of blue cheeses - but, I usually try to ensure that I have some Gorgonzola to hand; it is a great way of using up blur cheeses.
Sometimes, I will use a variety of cheese - they don't always have to be blue (but, for me, they usually are).
When the cheese was melted, I added some double cream, and, later, some of the liquid from the pasta cooking water.
Next in, was the shredded spinach, which was allowed to wilt.
Finally, the cooked pasta - today, I used orecchiette - was added, and mixed through. Candidly, any pasta will work well with this dish. I have also used the long pastas successfully.
Chopped walnuts will go exceptionally well with this dish; in fact, they are almost always served with the classic gnocchi and blue cheese sauce.
It is an easy, and incredibly tasty dish - one of the very few meals that can be on te table 30 minutes after one started preparing it.
