TAKE a pint of thin cream, rub a lump of loaf sugar on the outside of the lemon, and sweeten it to your taste, then put in the juice of a lemon, and a glass of Madeira wine, or French brandy, mill it to a froth with a chocolate mill; and take it off as it rises, and lay it upon a hair sieve, then fill one half of your posset glasses a little more than half full with white wine, and the other half of your glasses a little more than half full of red wine, then lay on your froth as high as you can, but observe that it is well drained on your sieve, or it will mix with your wine, and spoil your syllabubs.
