LORELAI: One minute it’s, “Pass the pot roast”; the next minute it’s, “Hey, have a pile of money”. Things are never boring at the Gilmore house.
Pot roast is an American dish made by braising a piece of beef, then slow cooking it in a covered dish with liquid added that can be made into gravy. Vegetables such as carrots, potatoes, and onions are commonly added as well.
The dish is a variation of the French dish boeuf à la mode, which was introduced by French immigrants to New England, and influenced by later German immigrants who also marinated and slow cooked roasts to ensure tenderness.
(The Gilmores didn’t really have pot roast that night, they ate rabbit.)
Lorelai is certainly right that being handed piles of money whenever you need them is part and parcel of being a Gilmore. She and Rory are supposedly struggling and working hard, but any time life gets a bit too tough you know someone will come along and bail them out financially.
