I used to get BBC-America on cable (when I could afford it) ... some selected BBC shows on my local PBS station. Not sure where I first saw Posh Nosh
... but I know I have seen it on both - usually as a filler between shows - episodes only average about 10-minutes.
This is not
Nigella Lawson - it is an irreverent culinary satire in the best tradition of British comedy (dry and subtle).
Here is a link to a BBC website for Posh Nosh
