Generally I take one egg when I make the egg nog for me only, but as now my friend is coming to meet me and I have decided to make egg nog for him. I want to know, should I add 2 eggs in the recipe or more than that? Do you think I can add some toppings to it for giving it a different texture? When should I serve the drink to him? Should I serve it hot or cold? I always drink it chilled but I am not sure whether my friend will like it chilled or hot?
