Plain melted Butter—very simple, but rarely well done.
Keep either a plated or tin saucepan for the sole purpose of melting butter. Put into it a little water and a dust of flour, and shake them together. Cut the butter in slices; as it melts, shake it one way; let it boil up, and it will be smooth and thick.
Another.
Mix a little flour and water out of the dredger, that it may not be lumpy; then put in a piece of butter, set it over a quick fire; have it on and off every instant to shake it, and it will not oil, but will become thick and smooth.
