Hibiscus blossom
From Tardis Wiki, the free Doctor Who reference
Hibiscus blossom was a rare honey, a jar of which Goronwy gave the Seventh Doctor when he left Shangri-La. (TV: Delta and the Bannermen)
However, this rare honey ended up becoming even rarer after Ace finished off the jar. (PROSE: Cat's Cradle: Witch Mark)
