If you subtract the tomato sauce and add ground pork (to the filling), sauerkraut, and smoked sausages, you get sarma, one of the unofficial Croatian food groups and a dish that's quite common throughout the rest of Central and Eastern Europe!
Generally considered to be winter food, months of cabbage roll bliss has to be meticulously prepared for seasonally with a massive barrel of fermenting cabbage. (Well, how did you think sauerkraut was made?) Once the cabbage is sour enough--keep in mind that it gets increasingly flavourful and tangy as time passes--just follow the directions above and remember: no tomato sauce!
But wait a minute... how in hell do you prepare sour cabbage in the first place? Well, I'm glad you asked since properly prepared cabbage is the key to delicious cabbage rolls! The idea is to immerse both shredded and whole cabbages in a saline solution strong enough to kill off pathogens while allowing beneficial bacteria to grow. If too little salt is used, the cabbage can spoil, but too much salt prevents fermentation! The sauerkraut is ready when no more air bubbles are at the surface of the cabbage.
So you have to go buy a bunch of cabbages, remove the cores and outer leaves, shred a few completely and fill the remaining whole ones with salt, pack all of it tightly inside a barrel or some kind of sealable container, and finally sprinkle some more salt to get the whole fermentation process going. In a few weeks you'll have delicious sauerkraut! Just thinking about it makes my mouth water!
That Yodel was so good, I wish I was eating it right now...
