Seed cake
From Tardis Wiki, the free Doctor Who reference
Soon before her death in 1893, Winifred Gillyflower offered the Eleventh Doctor seed cake, which he quickly declined. (TV: The Crimson Horror)
Behind the scenes
Though unremarked in the episode, the seed in question would almost certainly have been caraway, as the most common British meaning for "seed cake" is a "caraway seed cake".
