Put the rind of one lemon, cut very thin, into a saucepan, add 1 1/2 cups sugar, and pour one cup boiling water on to it. Add 1/2 oz. gelatine, softened previously in a little cold water, to the hot water and sugar, and stir over the fire until gelatine is thoroughly dissolved. Remove from fire and add 3 well-beaten eggs, and the juice of 3 lemons, then cook it over boiling water until the mixture thickens for about 20 to 30 minutes. Then pour into a wet mould and set in a cool place until firm.
