Every family has its own way of serving eggnog. In our family on Christmas Eve after coming back from church mom would serve us warm eggnog. Yes, mom served it warm and it was always so wonderful on a cold winter's night. That garnish of cinnamon stick, and the sprinkle of cinnamon, and nutmeg on the top always made it more special. And, yes, she added the alcohol after she saved some for the kids. So there usually were always two pitchers one with alcohol and the other was alcohol-free eggnog.
