[On Thanksgiving morning, Lorelai and Rory are walking toward the market]
RORY: What’s on the list?
LORELAI: Flowers for everyone we’re visiting and cranberry sauce for the Kims.
Cranberry sauce is a relish made from cranberries. In the US, the word “cranberries” refers to Vaccinium macrocarpon, a North American species of cranberry, grown commercially for its berries. Cranberry sauce in the US is more heavily sweetened than the tarter, more astringent version common in Europe. Cranberry sauce is traditionally served with turkey at Thanksgiving, and sometimes Christmas.
