Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Preheat the oven to 350°F (175°C).
In a bowl, beat the eggs and sugar together.
Add the sour cream, vinegar, raisins, cinnamon, cloves, and salt to the mixture.
Fold in the egg whites last.
Line pie tins with crust, fill with the mixture, and bake.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
