Hollandaise
sauce:
Place egg yolks,
wine and
vinegar in a round based mixing bowl.
Place bowl over a pot of simmering water and make a
sabayon by whisking rapidly until thick and creamy (don't
cook mixture to scrambled eggs).Immediately begin to whisk in the soft
butter, a 1/4 at a time. Don't allow it to get too hot. When
all the
butter is incorporated remove from heat.
Sauce should thick enough to coat a spoon. Finish with a squeeze of
lemon juice.Store in a
warm place until required and give it a whisk every now and then. This
sauce does not keep well so prepare just before using.This
sauce can separate so be careful.
