That's the one I heard about jenhal, although I don't think it hurts to rinse off the salt, as long as you keep the process rapid and 'light'.
The stewed red-cabbage-and-apple dish is a classic, and I can't stand it! I like cabbage crisp!
If I want red cabbage as a veg, I cook it just like the hard 'drumhead' white cabbage, but with a few drops of vinegar instead of salt.
