|"I show not your face but your heart's desire."|
- "Mrs. Weasley had sent [Harry] a scarlet jumper with the Gryffindor lion knitted on the front, also a dozen home-baked mince pies, some Christmas cake, and a box of nut brittle."
Nut brittle is a confection, usually very hard and brittle, which consists of flat broken pieces of hard sugar candy (usually brittle toffee) embedded with nuts. Molly Weasley gave Harry Potter a box of nut brittle for Christmas in 1993.
In British English, "candy" refers almost exclusively to hard sugar confectionery.
