Here’s a recipe for butternut squash, leek and blue cheese risotto that will surely warm the cockles on a cold winter’s evening. Nigel Slater has a recipe for pancetta and blue cheese risotto that I made once; it was really tasty but unfortunately so salty that I could only eat a couple of mouthfuls at a time. Here, the butternut squash and leek flavours are both mild and sweet and complement the blue cheese brilliantly. I used Stilton but you could use any blue cheese. Gorgonzola would make it a little more authentically Italian! A squeeze of lemon juice at the end finishes it off nicely.
