From the way he told the story, it sounded like he was robbing the cookie jar.
If you were craving Vitamin C, it would have been like robbing a cookie jar. I wonder if we crave sourness when our bodies want Vitamin C. Even with our modern complete diet, there are times I crave vinegar. Sometimes it is a whole sour pickle, pepperoncini or gardenaria; sometimes it is saurkraut.
OTOH, maybe it is the salt?
I used to hate kraut until my Czech husband showed me how it was done by the old timers. Since then, I have developed such a yen for the stuff that I am making it (or attempting to—some efforts are better than others) all the time. Yum! Zeli!
