Put two ounces of isinglass into a pint of water, and boil it till
it has dissolved. Then strain it into a porcelain skillet, and add
to it half a pint of white wine; the grated peel and juice of two
large deep-coloured oranges; half a pound of loaf-sugar; and the
yolks only of eight eggs that have been well beaten. Mix the whole
thoroughly; place it on hot coals and simmer it, stirring it all
the time till it boils hard. Then take it off directly, strain it,
and put it into moulds to congeal.
