Parsley sauce is a traditional British accompaniment for fish; a classic white roux is prepared before flavoured milk is gradually added to form the silkiest of sauces, before getting freshened up with lots of fresh parsley.

Peel and the onion, and then push the pointed end of the cloves into the onion before placing it in a small (15cm or 6") milk pan.
Bash the garlic with the flat side of a knife, and add it to the pan and add the bay leaf.
Pour over the milk and bring to a boil, then turn off and allow to cool for 10 minutes.
Chop the parsley as finely as you can.
In a second 15cm or 6" saucepan, melt the butter over a medium heat without colouring.
Add the flour to the melted butter and cook, stirring constantly, for 3-4 minutes. If the flour begins to go beyond light blond colour, reduce the heat a little. Do not rush this step; you need to "cook out" the flour so that your sauce does not taste like raw flour.
Remove the flavourings from the milk, then add the salt and white pepper and stir to combine.
Add the milk little by little to the roux base, starting with around 3 tablespoons. Stir constantly as you add the milk, and only add more once the previous addition is completely combined.Initially, the mix will look like it has split, but it will come together and form a paste. As you add more milk to the paste, it will thin to a beautiful white sauce.Be careful not to boil the sauce; if it is coming to a boil, reduce the temperature a little.This recipe makes a thick sauce. If you want to thin it out a little, add more milk.
Stir through the chopped parsley and serve immediately.
Notes
If you want to use the milk to cook smoked fish pour over the fish immediately and do not allow to cool.
