LEMON-HAZELNUT BUTTER SAUCE

Steps:

• Heat 2 tablespoons of the butter in a saucepan and add the shallots. Cook briefly, stirring, and add the wine, 3 tablespoons of the hazelnut liqueur and all the lemon juice. Bring to the boil and cook about 5 minutes or until reduced to 4 tablespoons.
• Gradually add the remaining 1/2 pound butter, stirring constantly with a wire whisk. When thickened remove the sauce from the heat and add the remaining 1 tablespoon of liqueur, salt and pepper.
• Put the hazelnuts into the container of a food processor or electric blender and blend as finely as possible. Add to the sauce.
