Another way.
One ounce of isinglass, dissolved in a good half pint of water, the juice of two small lemons, the peel of half a lemon, the yolks of four eggs, well beaten, half a pound of sugar, half a pint of white wine: mix these carefully together, and stir them into the isinglass jelly over the fire. Let it simmer a few minutes; when a little cool, pour it into your moulds, taking care to wet them first; turn it out the next day.
