Method

Although in some of the recipes the amounts will vary, the principal is the same. 

• In a thick based pan at a high heat, melt the butter and add the onions and the garlic, cook until the onions are soft (about 5 minutes). 

• Add the flour and stir with a wooden spoon until it thickens and the mix is starting to come away from the sides of the pan. 
• Slowly add the milk and stir until smooth. 
• Once all the milk is added turn down the heat and let it simmer for 2-3 minutes, then add in the mustard and the seasoning, salt and pepper to taste.  

You should now have a smooth white sauce that’s ready to be used for a variety of great dishes.
