Garlic is as Good as Ten Mothers
It's 51 minute foodie documentary from 1980 (and it looks it too).
It's a love story to garlic (which as depicted wasn't really a big trend in the US back in the 1970s and earlier if you believe the talking heads).
One talking head mentions that he believes that vampires are real. Werner Herzog also makes a cameo.
Lots of dialogueless food prep providing plenty of space for riffing.
