25 g butter
1 tbsp plain flour
150 ml milk
50 grams stilton or other blue cheese (chopped in small pieces or crumbled)
Optional: ground parsley or garlic salt
Melt the butter in a pan over a medium heat, stir the flour and let it cook for 1 minute. Pour the milk, stir constantly until the sauce is smooth and all the milk has been added. Bring the mixture to a simmer and stir the cheese. Cook until the cheese has melted and the sauce has thickened slightly, then season to taste and serve. You can also add ground parsley or garlic.
