Yeah, I read the same thing a long time ago, and that's the only reason I salted them. I keep my
salt intake very low, basically because I'm very sensitive to salt, ie, I can taste it when it's hardly there, soooo, I always decrease it a lot. I made sure I rinsed the eggplant slices really well - I almost drowned them. LOL.
The bitterness issue seems to be debatable. Some people say that eggplant is not as bitter today as it was in yesteryears, and therefore, doesn't need salting. I'm just afraid to take the chance, so I've always salted the eggplant on the few occasions I've used it. I also read somewhere that salting and letting them sit for awhile tenderizes them. I wonder....
By the way, I love your idea of using a cookie rack! Much better than using a colander.
