Ingredients

• 25g butter
• 1 tbsp plain flour
• 150ml milk
• 50g Cashel blue (or other blue cheese), roughly crumbled

Method

Put a pan on a medium heat, and add the butter, letting it melt slowly.

When the butter begins to bubble, stir in the flour until well-combined and let cook for a minute.

Using a whisk to stir the base, slowly pour in the milk, allowing for all the liquid to be combined before adding more to prevent lumps forming.

Bring the sauce to a simmer and let bubble for 2-3 minutes.

Add in the cheese and cook until it has melted and the sauce has thickened slightly. Add seasoning to taste and serve.
