I've just retrieved from the fridge, where they've been since I took them home from a party the Monday before Christmas (Monday is the start of the weekend among the circles I move in*), two flapjacks and two energy balls. All homemade, so no BB dates. Flapjacks obviously last forever. The energy balls are a mixture of seeds, cocoa, sugar, and butter or oil or some sort of fat. They're every bit as tasty as they were three weeks ago.
*It ends on Sunday, if you were unsure.
