This is not an inexpensive cream because there will be
needed the yolks of five eggs, two cups each of cream and maple sirup [sic].
Heat the sirup and pour over the yolks of the eggs that have been beaten until
light colored. Stir constantly while mixing the sirup and eggs, then
cook until thick like a custard. Cool in a bowl, stirring now and then. Add a
teaspoon of vanilla flavoring and two cups of cream. Freeze, using three parts
ice to one of salt.
