Does anyone have a recipe or even heard of Allegretto Cake or Algretta Cake(This I believe is a family recipe)?

The second one I know is a family recipe and only the women in that family is given the recipe for it. My understanding is it maybe made off of the first recipe and just tweaked a bit.Does anyone have a recipe or even heard of Allegretto Cake or Algretta Cake(This I believe is a family recipe)?
Website I got this from contains a typo in the frosting recipe. No idea how to fix it... But here it is:





ALLEGRETTA FRUIT CAKES





I cup pastry flour


4 tablespoonfuls butter


I cup boiling water


4 eggs





Put the water and butter into a saucepan over the fire, and when actively boiling add flour all at once, stirring rapidly all the time until the dough leaves the sides of the pan and forms a large ball. Cover and set to one side to cool. Now add one egg at a time, beating well each time. The dough should look fine, velvety, and glossy. Dip by teaspoonfuls on to greased baking pans and bake in a moderately quick oven about forty-five minutes or until very light. Fill the space inside with sliced peaches, fruit, or any desired filling. A very small opening is required on the side of the puff for filling. Cover well with allegretta frosting.





ALLEGRETTA FROSTING





2 whites of eggs


I teaspoonful vanilla


1J cups powdered sugar


I teaspoonful lemon juice


3 squares unsweetened chocolate





Break the whites of the eggs on to a cold platter, beat well, lifting the egg beater high to entangle air for lightness. When very frothy, commence adding the sugar, a very little at a time, and keep on doing so, beating hard until it will stand alone. Add the lemon juice, beat, and let stand until stiff and shiny, then add the vanilla. Spread this on each puff and let stand until dry. Heat the chocolate in the bowl over the teakettle of hot water, or melt in a double boiler.





When the icing is not soft on top of the puff, take your spatula and dip up plenty of the chocolate on the broad blade, and with a quick sweeping motion cover every bit of the icing with it. This will have to be repeated several times to cover all the icing.





This is a delicious frosting or filling, and can easily be made with a little practice. Any good cake recipe is nice, baked in one sheet, iced, and spread with chocolate and decorated with nuts; cut in squares.
