To melt Butter.
On a clean trencher, mix a little flour to a large piece of butter, in the proportion of a teaspoonful to a full quarter of a pound; then put into a saucepan, and pour on it two large spoonfuls of hot water; set it on the fire, and let it boil quick. You should stir it round one way, and serve it as soon as ready.
On the goodness of this depends the look and flavour of every sauce in which it is put.
