1. Just before serving, combine eggnog and softened ice cream.
2. Slowly add 7-Up.
3. You can add a little extra “flavor” by putting some brandy or whiskey directly into the punch. Or, if you are having guests who don’t drink alcohol, you can have it handy and they can add it if they want.
4. I always put it in a pretty decanter right next to the punch bowl.
