Fish fingers and custard

Fish custard was a dish enjoyed by the Doctor shortly after his regeneration. Having tried and hated multiple foods from young Amelia Pond's kitchen, the Doctor found frozen fish fingers and custard. He enjoyed them together, dipping the fish fingers into the custard. Amelia took the Doctor's enjoyment of fish custard in stride, which he noted as a sign of her bravery.

When the Doctor rejoined Amy Pond as an adult, he realised it had been "14 years since fish custard." (DW: The Eleventh Hour)

Behind the scenes

 * Matt Smith initially claimed it was actually fish fingers and custard he was eating, and that he found it "gorgeous." He later admitted the "fish fingers" were actually breaded cakes.
