Melt 1 tablespoon of
butter in a double-boiler over medium heat. Add the eggs and stir continuously with a whisk until they thicken with small curds. If curds start to form too
fast, remove the pan from the heat for a while. When thick, add the remaining tablespoon of
butter and continue stirring until melted and blended. Test for
salt and
pepper. Add the
chives [optional].
