2 shallots, peeled and finely sliced

1 T. white wine vinegar

2 T. lemon juice

4 T. white wine

1 T. cold water

8oz salted butter, cut into cubes

Plenty of finely snipped chives

 

Place the finely sliced shallots, wine vinegar, lemon juice and white wine in a saucepan. Bring to the boil and reduce the liquid until you have about 2 T. Add the cold water and reduce again until you have 1 T. liquid. Turn the heat down and, over a low heat, slowly whisk in the butter, about 25g (1oz) at a time. The sauce will emulsify (thicken and lighten in color). Once all the butter has been added, remove the pan from the heat, then pass the sauce through a sieve into another saucepan. Set aside until needed, but do not refrigerate or the sauce will separate. To serve, gently reheat the sauce, stirring continuously and add the finely snipped chives.
