Turbriskafil

From The Big Bang Theory Wiki

A (hopefully imaginary) dish that Howard's mother makes for Thanksgiving every year. It consists of a combination of three (real) dishes: turkey, stuffed with a brisket stuffed with gefilte fish.

While Raj, who usually celebrates Thanksgiving at Howard's place, apparently has no problem with this dish, Howard claims that it's "not as good as it sounds" and that he doesn't even chew it and just swallows it "like pills" (0304).
