Mustard Sauce
This sauce has the great advantage that it does not require any cooking and can be produced within a few moments if desired.
Two yolks of eggs carefully separated from the whites and placed in a stone basin, and two teaspoonfuls of dry mustard stirred together till perfectly smooth with two large tablespoonfuls of best salad oil and two tablespoonfuls of best malt vinegar and a pinch of salt. Sprinkle on it a little finely chopped parsley the last thing.
