March 8th : ENGLISH RUM SHRUB
To three gallons of best Jamaica rum add a quart of orange juice, a pint of lemon juice, with the peels of the latter fruit cut very thin, and six pounds of powdered white sugar.
Let these be covered close, and remain so all night; next day boil three pints of fresh milk, and let it get cold, then pour it on the spirit and juice, mix them well, and let it stand for an hour.
Filter it through a flannel bag, lined with blotting paper, into bottles ; cork down as soon as each is filled.
