Wait, "quartet" is four, but if they're talking about "sugar and spice" related to a group of four, maybe "sugar and spice quartet" refers to a group or a song. For example, a musical quartet that uses sugar and spice in their theme, or a story about four characters. Alternatively, perhaps a children's book or a recipe collection. But the user added "qartulad." Maybe the "ad" is a suffix, making it an adjective? Like "quartulade" as an adjective. Not sure.
