There is something magic in a homemade Christmas cookie.
The store-bought variety is practically everywhere just now, even in shops that don't normally sell food. Some of them will be perfectly all right, and a lot of busy folks will settle for them, especially if they've been gifted with a tin.
But bought cookies just don't have the conjuring power of those that are homemade. Bound up in warm nostalgia that may have no place in reality, a homemade Christmas cookie will even stir up people who don't keep the holiday or especially care for sweets.
