Creamy spinach and stilton soup

Melt the butter in a large saucepan and sauté the spring onions for about 2-3 mins until softened, but not browned.

Add the spinach and vegetable stock and heat until almost boiling. Reduce the heat and simmer, covered, for 5 mins.

Transfer the mixture to a blender or food processor and add the soft cheese. Blend for about 15-20 mins until smooth and velvety. Return to the saucepan.

Blend the cornflour with 3-4 tbsp of the milk and add to the soup with the remaining milk and most of the crumbled Stilton. Bring up to the boil, stirring constantly until thickened. Reduce the heat and cook gently for 2 mins, then season to taste with salt and pepper.

If serving hot, ladle the soup into warmed bowls. Serve at once, garnished with the soured cream or yogurt, the reserved Stilton and chopped fresh spring onions and parsley.
