Psycho Donuts, which has locations in Campbell and San Jose, said the "foie bomb" pastry consists of a doughnut hole stuffed with foie gras mousse and pierced by a glass pipette containing balsamic gastrique, fig and honey, ABC News reported Wednesday.
A single salted and fried sage leaf rests on top of the treat.
Ron Levi, Psycho's doctor of donut derangement, said a limited number of the foie bombs will be available.
"We're planning on doing 100 of them, depending on how much foie gras mousse I can get," Levi said.
