Recipe and photos updated on July 17, 2017. I think this version is better, but if you're looking for the original, email me at firstname.lastname@example.org. If your eggplant is any larger than 1 pound (assuming you're doubling the recipe or only using part of a larger eggplant), or has a significant amount of seeds, consider salting it before marinading. This will draw out any excess bitterness that the seeds develop as they age. You will likely have more tzatziki than you need. It should keep in the fridge for a few days. You can also seal it up and freeze it, or use it for another batch of these later in the week, or as a salad dressing.
