twice a day, not much, like a few chop stick grabs.

Since I am slow to respond and the post is a bit old, this is what I said to the guy who asked me how I make it

Pretty basic, I buy 3 or 4 heads of chinese cabbage. Dice it up in to 1 inch squares roughly. Add grated carrots, ginger and onion (and garlic, 2 or 3 whole heads, forgot to mention this to other poster). I then soak that all in salty water (about the same saltyness as the ocean) for about 4 hours. Then I rinse it all twice. Finally I add three or four table spoons of dried red peppers finely ground, three or four table spoons soy sauce, three or four table spoons fish sauce. Finally I put it in a big pot and let sit at room temperature in a dark room for 48 hours. After that into jars and into the fridge. I eat it twice a day usually breakfast and dinner, not even that much. After years and years of lansoprosol, omeprosol and xantac, and tums tums tums, not one hint of heart burn since.
