I've read that eggplant can be bitter. I want to make a roasted eggplant dish this evening, should I salt the eggplant first? Dry brine or wet?
I wouldn't use a wet brine...they're like sponges and you'd end up with a salt brick.
Look at the seeds, if they're brown older seeds you probably need to salt, rinse and dry.
If they're mostly younger white seeds, you could skip it.
