After 10 years of experimentation, I have finally figured out that medium-sized round eggplant is the best. Too small, and they are bitter. Too big, like in the photo above, and they are soft, tasteless, and the seeds are too big and numerous.
The seeds are actually an important taste component. They can be big, they can be numerous, but they can’t be both because it makes the overall texture too soft. This is something nobody ever mentioned to me.
Something really interesting – I’ve seen people have allergic reactions to only the big ones. Specific symptoms were an itchy and swelling throat.
So stay away from big round eggplant!
