First stir with the ladle the yolks and the sugar until they become almost white, then add the wine. When ready to serve, place the saucepan in another one containing hot water and beat until the sugar is melted and the egg begins to thicken.
SYRUPS
(Sciroppi)
The syrups of acidulated fruits, diluted with ice water are refreshing and pleasant beverages, greatly appreciated during the summer months. It is well, however, not to drink them until the digestion is completed, because they may disturb it, on account of the sugar that they contain.

RED CURRANT OR GOOSEBERRY SYRUP
(Sciroppo di ribes)
Remove the stems from the bunches of gooseberry and place them in an earthen vase, to be kept in a cool place. When it has begun to ferment (which may happen after three or four days) sink the surface film and stir with a ladle twice a day, continuing this operation until it has stopped raising. Then put in a cheese cloth, letting the juice come out through pressing with the hands or in a machine. Pass the juice through a filter, two or three times if necessary, until you obtain a limpid liquid. Then put it on the fire and when it begins to boil pour in it granulated sugar and citric acid in the following proportions:
Liquid, six pounds.
Sugar, eight pounds.
Citric acid, one ounce.
That is to say for each three parts of the liquid, add four parts of sugar, and one ounce of citric acid for eight pounds of sugar mixed with six pounds of liquid.
