This is my great-grandmother's recipe.
Ingredients
10 eggs
2 cups sugar
1 oz of spirit per serving - can use gin, rum, brandy, or cognac (I prefer genever, or rye)
1 tsp vanilla extract
1 dash nutmeg
Process
Crack eggs into a bowl, whisk until mostly uniform.
Pour in sugar.
Double-boil eggs and sugar, stirring continuously (takes about 3-5 min).
Add vanilla and nutmeg.
Blend briefly, serve.
Stir in 1 oz of spirit of choice into 4 oz serving
2017 variant: use 1/2 tsp vanilla, 2 dashes nutmeg, 2 dashes cinammon, 1 dash pumpkin pie spice
