There was a BBC series many years ago called Tenko, about a group of Western women in a Japanese internment camp in 1942. In one scene, the women are sent to clean out the latrines as a punishment. It was, er, very realistic. When asked in an interview how they set the scene up and what they used as the, er, stuff they had to scrape out, one of the actresses (Stephanie Beacham?) said "oh, it was quite pleasant; we used crunchy peanut butter!" Genius, when you think about it.
I can never see PB without thinking of this. Having said that, I love the stuff and I only limit the amount I have because I am trying to lose weight and it is very high in calories. PB and 'jelly' (jam) sandwiches are the food of the Gods, a wonderful sweet/savoury mixture. And thick, crunchy PB on toasted sourdough is .. beyond wonderful.
