To boil coffee and refine it, put the necessary quantity of water into a pot which it will not fill by some inches; when it boils stir in the coffee; for unless this be at once moistened, it will remain on the top and be liable to fly over. Give it one or two strong boils, then raise it from the fire, and simmer it for ten minutes only; pour out a large cupful twice, hold it high over the coffee pot and pour it in again, then set it on the stove where it will keep hot without simmering or moving in the least, for ten minutes longer. It will be perfectly clear, unless mismanaged, without any other fining. Should more, however, be deemed necessary, a very small pinch of isinglass, or a clean egg-shell, with a little of the white adhering to it, is the best that can be used. Never use mustard to fine coffee with. It is a barbarous custom of which we have heard foreigners who have been in England vehemently complain.
Remark.— Filtering is, we should say, a far more economical, and in every way a superior mode of making coffee to boiling it; but as some persons still prefer the old method, we insert the receipt for it.
