Pare off very thin the yellow rind of a dozen large lemons; throw the parings into a gallon of white brandy, and let them steep till next day, or at least twelve hours. Break up four pounds of loaf-sugar into another vessel, and squeeze upon it the juice of the lemons. Let this too stand all night. Next day mix all together, boil two quarts of milk, and pour it boiling hot into the other ingredients. Cover the vessel, and let it stand eight days, stirring it daily. Then strain it through a flannel bag till the liquid is perfectly clear. Let it stand six weeks in a demijohn or glass jar, and then bottle it.
To make it still more clear, you may filter it through a piece of fine muslin pinned down to the bottom of a sieve, or through blotting paper, which must be frequently renewed. It should be white blotting paper.
