Allegedly-- Ice cream-- is an american dessert-- there have been "cool" or Iced desserts going back to antiquity-- but none other than Dolly Madison is said to have "introduced" ice cream to the world-- and putting ice cream on pie was the "all american dessert" (so the missing word is a la mode american.) This, while the US government was still in Philadelphia. Philadelphia style ice cream is a custard (cream and milk* cooked with egg till it thickens, and then instead of being baked--it is chilled and frozen.) Most ice cream today does not have this "custard' base. (*more cream than milk in the mixture)

and thanks Bob for spigot-- i was beginning to think i was the only one who had ever used the word! I would say SPIG (like pig)ott.
