Horseradish
From Tardis Wiki, the free Doctor Who reference
Horseradish was a food item. Lucie Miller's Auntie Pat put horseradish on chocolate digestives because she liked foods that were "stinky". (PROSE: The Great Escapes)
It was sometimes made into horseradish sauce. (PROSE: Verdigris)
The Fourth Doctor preferred horseradish over apple sauce. (PROSE: Earth)
