This Harper's article from 2005 compares the food porn of the Food Network to regular porn.
Eventually, Tyler and the housewife would go cheek to cheek, lean forward, open their mouths, taste the chicken and rice, and melt into a flushed-face, simultaneous food swoon.

"Classic porn style," said Nitke. "They're stretching the moment out, the orgasmic moment. In porn they'll take a cum shot and run it in an endless loop."
That must have been a fun one to write. See also: Food Network star or porn star? (via serious eats)
