Kale in kraut-great idea. I often have to fish out the kale ribs and broccoli stems from the
compost that my wife puts in there to put them in the kraut. Before bland and fibrous, after, briny, juicy and savory. PLus-free probiotics.
Bitter melon, like amla-Indian gooseberry, and nopales-cactus pads, are pretty hard to eat raw, but
medicinal. When bitter melon is made to be part of sauerkraut, it is juicy, salty, sour and savory, with just the slightest hint of bitter. You have to strain to sense the bitter. They taste great over green salad, which by itself, is not so flavorful.
I have noticed the correlation over time that many different Asian ethnic groups will eat things not because they taste great but because they're healthy. Then they will explore recipes on how to make that taste good. Is it surprising that the Japanese are much healthier and long-lived than Americans?
