One gallon of milk, one dozen of eggs

From 1889:

Mrs Justice Field was a Maryland girl and she gives a recipe that speaks of the old days of hospitality. It is egg-nogg or the “greeting cup” and in Maryland and Virginia houses is sent around Christmas morning to every room before breakfast.

Maryland egg-nogg:
One gallon of milk, one dozen of eggs. Divide the yolks from the whites and beat them. Add fifteen tablespoonfuls of sugar, one grated nutmeg, one pint of brandy, one pint of Jamaica rum. Beat the yolks and sugar until light, add the brandy and rum, stirring constantly. Last of all put in one gallon of milk or cream and cover with the beaten whites of the eggs.
